The things that are most impressive as far as I'm concerned are a couple of moon-based coincidences - that the moon covers the sun so well during a total solar eclipse, and that 28 days give or take is the moons orbit round the earth and that 28 days is a human menstrual cycle, give or take.
This isn't evidence for an Abramic creator - in fact it isn't evidence for any kind of creator really - but I think its the best evidence there is that there might be a creator rather than just boring blind chance.
I accept that there are a hundred cool coincidences related to just about anything you care to name - but I think there is some special resonance here that links the sun, the moon, human biology - that is pretty impressive.
As an aside, does anyone else know any cool moon-related coincidences that might sit along side these nicely?
