Believing in anything is an act of faith. Irrationality is yet to be demonstrated by the submission of your proof that abiogensis had to happen by the spontaneous formation of a prokariote. A submission that is still, I believe, on your to-do list.
Then I'll be more specific. Believing in abiogeneis is an act of faith not an act of material rationality, and material rationality is the the arena science restricts itself to. I have no quarrel with you about this, until you transmute this personal opinion of yours into a statement about what science believes. :-)
Materialism is a faith. It is a very irrational faith. In no way should it be axiomatic. If you agree that God's existance should be an axiom, I'll stop arguing with you.
