The first example I thought of was the solar eclipse. The conditions you need to produce a solar eclipse also make Earth a habitable planet.
This is the point where my BS meter pegged. The sizes of the lunar and solar disks as seen from Earth is pure cosmic happenstance. We are lucky that the similarity of those apparent sizes makes eclipses spectacular. This coincidence has no effect whatever on the development of life. If it did, then why don't we get serious environmental effects from annular eclipses?

Didn't seem right with me either. However, the moon's rotation is such that we on Earth only see exactly 1 face of it has to be math wise an astronomical figure of that occuring anywhere.
