The Origin of Life is Speculative
The question of the origin of life is essentially speculative. We have to construct, by straightforward thinking on the basis of very few factual observations, a plausible and self-consistent picture of a process which must have occurred before any of the forms which are known to us in the fossil record could have existed.We have no fossil record of the origin of life, we are left only to attempt to recreate it in the lab, but we won't know if we got the process right.
