Everything I have ever seen has obeyed the laws of nature. Nothing I have ever seen has been supernatural. Nor have I ever heard a
verifiable report of a supernatural event. Hence, I have the
strongest possible empirical grounds for the conclusion that the origin of life took place within the laws of nature rather than in violation of them. Faith is not required.
You yourself would take this attitude most of the time. If you saw a conjuror make an elephant disappear, and you didn't know how he did it, you wouldn't conclude that he really had magical powers, would you? But when you come across something in biology you don't understand, then its time to roll out the good ol' god-of-the-gaps fallacy: because when it comes to religion, you need to play by different epistemological rules.
As far as the origin of life goes, you might want to look up what happens when you mix amino acids with Q- replicase. No deities are involved.
