Aren't the Chances of Life Forming Randomly Less Than 1 in a Trillion?

This claim is based on the calculations of all of the millions of molecules in a single cell forming by chance. No scientist believes this is how life formed. Instead, most theories of "abiogenesis" begin with simple self-replicating peptides. The smallest self-replicating peptide is only 32 amino acids long. It can and does form naturally, and has the ability to replicate itself, just like DNA. It is believed that a similar molecule formed the first stages of life. After many thousands of years of adaptations, all governed by the non-random process of Natural Selection, did the first microbe finally develop.
