I believe on creationism "and" abiogenesis, instead of "versus".
I guess I would need to understand how you are defining those terms before I could fully grasp the argument.
If life popped into existence, fully formed, per creationism, then that would seem to run counter to abiogenesis (life from non-living matter).
Similarly, if life could have evolved from non-living matter, then how is a creation hypothesis even necessary?
I'm not sure we can have both at the same time.
And picking the subject of the other thread, what's the science's answer to the question: Why are we here?
IIRC, the question I offered to discuss is "how did we get here", not "why are we here". If you'll recall, I indicated that I consider the latter to be something of a silly question.
Regarding the former, I recommend this (
