I'm sorry. It was meant to be a similar analogy... an application of Occam's Razor.

Moses without benefit of a microscope either came up with the idea that he should wait till the eighth day on his own which I find unlikely, established it coincidentally which I also find unlikely or he had the benefit of enlightenment from a higher power.

This is evident because we now know that the eigth day just happens to be the day you can safely do the circumscision with the least risk of the little fella bleeding to death. I chose Moses as an example because Muslims and Christians can normally find common ground when it comes to him.

My understanding of Chapter 17 of the Quran, Mohammed establishes that Allah spoke to Moses, gave the land of Israel to the Jews and prophesied that he would restore it to them at the end of days.

Of course, I'm starting to think the simplest explanation for the speed you exhibit at answering Trivia must be divine intervention. So perhaps the with which I jump to divinity as explanation could be used to deflate my logic.
