I got myself into a discussion between creationists and evolutionists. I myself am an evolutionist. I am not a biologist or a scientist in any way, hence I'm asking you for help.
So this creationist gave me an argument why Darwin could not be right.
What he said was in dutch, so I'll try to translate it:
DNA is built upon amino acids. There are 20 different amino acids. amino acids can be created by nature. |
Now we assume that a good protein is 300 amino acids long. Proteins are created by putting amino acids together. The chance that the right amino acid gets on the first place of a DNA string is about 1/20. The same for the next amino acid. Which means the total chance is (1/20)^300. Estimated is that the universe is 5 billion years old, which is 160 trillion seconds. I round up to 1000 trillion, I can give away a few trillion, you'll see later. Which means it's 10^15 seconds old.
The total amount of atoms in the universe is 10^80.
from here I really stop getting it so I'll translate litterally
one million reactions per second is 10^6 total. This makes it 10^103 chance, I need 10^390 which is 10^287 short. So basically the chance that dna created itself is REALLY REALLY SMALL
Is this a valid calculation? Is he correct or is he missing something?
Like I said, I don't know anything about this subject so I'd really appreciate your help!
