Coppedge calculated the probability of a single polypeptide forming into an amino acid at 10^-23. You need hundreds of thousands of these for a single cell organism. So the probability of life forming by chance here on earth was on the order of 10^-trillion-trillion-trillion.

There may be billions of life-capable planets but that just shaves off 9 orders of magnitude off the probability.

Which makes one wonder - why is NASA expending so much money to "find evidence" of life? Why is this important to them?

Any engineer can tell them that nothing that functions well is accidental.
