No different from modern folks, who have resorted to Darwinian macroevolution to explain origins.
There is copious evidence for the scientific theory of evolution.
The universe looks like it was made for the purpose of supporting life.
I guess that's why almost all of it is inhospitable to life.
It isn't enough just to look like it has a purpose, we need confirmation.
It
doesn't look like it has a purpose.
That's the main point I was making, which still stands, regardless of the question, "well who created the creator?"
Your point appears to be non-existent. The is question is relevant to any unevidenced story of an unexplained creator; such stories don't explain anything at all - except in a childish just-so story kind of way.
The Christian claim is that the bible provides that confirmation.
The bible is incoherent and self-contradictory - as are most versions of Christianity.
