Life by Accident

Life by Accident

The odds of random life are so improbable, believing it requires a gigantic leap of faith.


The Exodus from Egypt, culminating in the receiving of the Torah, is the foundation of our faith.

Others religions around the world also have pivotal events from which much of their theology emerges. Atheism is no different. For an atheist, the accidental, spontaneous generation of life from inanimate minerals is essential to their core beliefs. It is the foundation of the philosophy that people are no more than a collection of simple particles. Just as non-living particles have no moral responsibilities; neither do the humans that contain them. Their premise is that the span of hundreds of millions of years from the beginning of planet Earth to the present is quite long enough for generating the millions of species we find here [1]. The only alternative to life by accident is the existence of a Creator which would be unacceptable to them.

Thus, just like the Jews stand upon the Exodus from Egypt emerging from slavery to freedom, so do the atheists rely on their Exodus from the Primordial Soup of mud to salamanders as the foundation of their faith.

Many arguments can be advanced that seriously question the feasibility of accidental life. I would like to approach it from a mathematical probability standpoint. I would like to show that the improbability of accidental life is so enormous, that to believe in it requires a gigantic leap of faith.

Let me start by admitting that I am not nearly smart enough to calculate the probability of creating life. But I can study a much simpler problem and show that the simpler problem is surprisingly impossible, from which we can infer that the more complicated problem is at least as impossible.

Consider an ordinary deck of playing 52 playing cards. Let's presume that if we could generate a certain sequence of cards accidentally, then we could also generate life accidentally. After all, a fundamental key to life is DNA, which is a long string of molecules strung together. The smallest known DNA string has over 490,000 nucleotides [2], each nucleotide being itself a very complicated structure [3]. This is may be like comparing scaling Mount Everest to climbing a six-foot step-ladder. But let's see what happens.

So, for starters how many ways can we arrange a deck of cards? Start by selecting one card. Since there are 52 cards in the deck, you have 52 different ways of selecting the first card. Now, select another card. There are only 51 left. So for each of the 52 ways you could have selected the first card, there are 51 more ways of selecting a second card. For two cards, there are 52x51 or 2652 combinations. There are now 50 cards left for the third selection for a total of 50x2652 or 132,600 combinations. Repeating this pattern for all 52 cards gives the total number of combinations as 52x51x50x49x...x1. This pattern is called a factorial in mathematics. A spreadsheet program will compute this quite readily giving the result 8.06x1067 (give or take a few vigintillion [4]).

Well what does that mean? Basically, it is 8 followed by 67 zeros. The problem with numbers this big is that it is hard to get an appreciation as to how enormous they really are. To get a glimpse of how hard it would be to get one specific series of cards out of all the possibilities we'll do a little thought experiment. Let every atom on planet Earth help us generate combinations of cards. Note that about 100 trillion iron atoms can fit on the top of a pin (see [5] for the size of a pin and [6] for the size of an iron atom). That's a lot. But how many atoms are in the whole planet (which is much bigger than the head of a pin)?

This is not too hard to figure out (though you may want to skip to the next paragraph if math makes you queasy). The mass of the Earth is 6x1024kg [7] and the Earth is made up of various elements in various proportions [8]. From these two facts we can get the mass of each element. From a periodic table of elements, we can find the atomic mass of each element [9]. Dividing the mass by the atomic mass gives the moles of each element (remember to convert the mass from kilograms to grams). Multiplying moles by Avogadro's number (6.02x1023 atoms/mole) [10] gives the number of atoms of each element. See the following table for the results of the calculations.



Total Mass

Atomic Mass



















































Well, if you survived that we can now get to the fun stuff. You see, there are about 1.3x1050 atoms on our planet. Let's give every atom on the planet a deck of cards and instruct each atom to shuffle those cards once per second. Now with the cooperation of every atom on the entire planet in our miniature life-generating experiment, how long do we have to wait to get our single string of cards? The answer is simple. Take the number of card combinations and divide by the number of atoms on the planet. 8.06x1067 / 1.3x1050 = 6.2x1017 seconds. Given 60 seconds per minute, 60 minutes per hour, 24 hours per day, 365.25 days per year. This experiment will take 19.65 billion years! Scientists give our universe only 14 billion years [11]. We cannot get one series of a deck of cards within the age of the Universe. We cannot climb our step ladder, let alone scale Mount Everest.

We cannot get one series of a deck of cards within the age of the Universe.

There are several things that made our experiment much easier than the real-life situation. For example, we used every atom of the Earth, not just the small fraction of stuff on the surface. It is also important to note the explosion of improbability in our experiment. Just for laughs, let's add the jokers to the deck of cards (just two more cards for a total of 54). Now the experiment will take 2862 (i.e. 53x54) times longer, 5.6 trillion years, or about 4000 times the age of the Universe! Don't hold your breath.

Since this was so much fun, let's take it one step farther. We will add 21 more cards for a total of 75. Rather than comparing scaling Mount Everest to climbing a six-foot ladder we will use a nine-foot ladder.

Now to be fair to the atheists, we will make a "minor" concession. Rather than using every atom in the planet, let's use every proton and neutron in the Universe. Note that the Earth is an insignificant spec of dust in our Solar System, most of which is dominated by the Sun. The Solar System is lost among the 300 billion stellar systems of our galaxy, the Milky Way [12]. And the Milky Way is but a tiny dot in the Universe. So you would not be surprised to find out that there are quite a number of protons and neutrons in the entire Universe. Counting them is actually very easy. An upper limit to the mass of the Universe is 1.6x1060kg [13]. The mass of a proton or neutron is roughly 1.6x10-27kg (10-27 = 0.000000000000000000000000001) [14]. Dividing the mass of the universe by the mass of a proton gives 9.58x1086 protons and neutrons in the Universe. But before we set the Universe off to work on our experiment of generating one specific sequence of 75 cards, we will make one more concession. We will give each proton and neutron 1000 decks of cards.

Ready, set, GO! The Universe is shuffling away, 1000 times per second for every proton and neutron in the Universe, 9.58x1089 total shuffles per second. How long do we have to wait? It all depends on the number of combinations in 75 cards. Similar to our earlier computation, the answer is 75! (Not an exclamation, but rather the mathematical symbol for factorial). 75! = 2.5x10109. Whoa! (That is an exclamation). 2.5x10109 / 9.58x1089 = 2.6x1022 seconds or 820 trillion years, 58610 times the age of the Universe! (There's another exclamation) This gives new meaning to the term: Fat Chance.

Forming a single DNA strand is extremely more complex than lining up a few playing cards. And DNA itself is not life. It must exist within a living cell that has ribosomes, plasmids, cytoplasm and all sorts of other stuff. (Check out the picture on Wikipedia [15].) To expect all of this to have occurred on our humble planet within a mere few hundred million years requires a tremendous leap of faith most people would not prepared to make.

check ur facts

1. a solar year is 365.2524 days
2. with ur background in physics you actually gave a number for mass of the universe? the universe is constantly expanding!
3. evolution isn't random
4. learn the basics of card counting. the formula has changed since the MIT blackjack team rewrote it in the early 90's
5. never use wikipedia as a source

How did you figure the numerator?

All that math comes up with the number of possible combinations in a deck. You seem to assume that only one of these would "work." I don't think we really have any idea how to make a meaningful odds ratio.

In response to Joe #20

We certainly should find an enormous number of intermediates in the fossils record. The fact of most mutations being lethal is completely irrelevant and, respectfully, the fact that you mention shows your own lack of understanding. If intermediate forms existed for many millions of years and then died out, their fossils need to exist in great numbers, in proportion to the number of other fossils from the same time period (and adjusted for population size).

Creative Evolution

Since valid evidence for evolution does exist, why can we not accept is as one of the mechanisms of ongoing Creation, put in place by the Creator? When mutations are called "random", this means we humans cannot predict them (although under some circumstances they are more probable than others), but who is to say they are not planned by G-d? I believe that the Creator put the evolutionary mechanism in place so that ever new patterns of life could form. Daily in the Shacharit prayers we give praise for the "renewing of creation night and morn" - and evolution is part of this.

Science and Theology do live together.

I was wondering if any of you have ever heard of Sean B. Carroll, professor of genetics at the University of Wisconsin-Madison and his contributions to the science of Evolutionary Development? In his book, "Endless Forms Most Beautiful", Carroll states, "For more than a century, biologists had assumed that different types of animals were genetically constructed in completely different ways. Despite their great differences in appearance and physiology, all complex animals - flies, flycatchers, dinosaurs and trilobites, butterflies, zebras and humans - share a common "tool kit" of "master genes" that govern the formation and patterning of their bodies and body parts." This discovery opens up an entirely new way of looking at evolution. Quoting further, Evolutionary Development or EVO DEVO, now understands "how complexity is constructed from a single cell into a whole animal." Further, Carroll says that "around 3 percent of our DNA is made up of about 100 million bits of this regulatory code. This code determines when, where and how much of a gene's product is made. Regulatory DNA code is organized into fantastic little devices that integrate information about position in the embryo and time of development. The output of these devices is ultimately transformed into pieces of anatomy that make up the animal forms. This regulatory DNA contains the instructions for building anatomy, and evolutionary changes within this regulatory DNA lead to the diversity of form. EVO DEVO can now, scientifically, trace the modifications of structures through vast periods of evolutionary time-". Although this may seem like a startling development for Creationists, I see this as more incredible evidence of Intelligent Design rather than spontaneous generation of life. God's truth, in His divine creation of all things is perfection. The earth is God's creation of the natural elements of perfection. He then supplied earth's perfection with a "universal tool kit" to populate it with creatures, male and female. God knew exactly what to put into that "universal tool kit" to make it possible for living beings to evolve over 15 billion years within the perfection of earth's nature by the natural selection process of His design. What God provided was a way for living things, in all shapes and sizes, to be created, for all kinds of purposes, to be governed by His will. Those who believe that we rose up out of the primodial soup and those who believe in the devine hand of God's creation are both correct. I see no contradiction of theology nor a decided win for science. What I do see is a confirmation of God's incredible wonder and power in His divine creation, control and sustenance of all things. I see this new information as a way to bring theology and science closer together so that the discussions about evolution can become less intense and more productive.
