"Believing in" abiogenesis is as illogical as rejecting it. The fact is that we simply do not know how life came into existence. Or even what the structural parameters of it might be.
Yet on the balance of probability the three main competing hypothesis are examined, and only one stands out.
1) The untestable hypothesis that a non quantified supernatural entity, created, with un quantified process called magic God powers, all life on earth. Creationism.
2) The testable hypothesis that life originated on another planet and was relocated here via asteroid/comet impact. Panspermia.
3) The testable and now supportive evidenced hypothesis, that living chemical systems, arose from non living chemical processes. Abiogenesis.
1 Is just absurd. Irrational.
2. Just pushes the question back one step.
3. Is looking more and more likely, since the first Miller Urey experiment.
