The Bible is the claim, not the evidence

Follow up question: if pre-earth conditions are not observable nor measurable how can science correctly recreate them in order to prove RNA can spontaneously exist?

Because to prove RNA can spontaneously exist, all that need be done is to prove that RNA can spontaneously generate: no matter their knowledge of the initial conditions, if it's proven to have happened, then there's no more excuse to posit a god, merely because spontaneous generation seems impossible. It's not.
