Why Something Rather Than Nothing?

[Whateverist]

Abiogenesis then is "based" on a metaphysic, in this case a materialistic one.

If this philosophical assumption were to be proven false, would you accept that abiogenesis may be impossible, and that no amount of future scientific research will demonstrate it?

Is your premise even something that could be proven false? You could never rule out abiogenesis. All you could do is rule out various formulations based on attempts at simulation.

So sure, a proof -if valid- is an excellent reason to believe something. The trouble is proofs rarely succeed outside of math and logic.

But lets ignore that and assume somehow we could 'prove' abiogenesis impossible. What would you then assume about the beginnings of life?
