The point as best as I can see was that the moon can perfectly eclipse the sun. The two have almost precisely the same apparent size in the sky.
Earth is sitting in quite a lot of other physical sweet spots, without which life-as-we-know-it couldn't have existed -- "evolved" or not.
Bingo. We could be discussing this only on a planet that has a "sweet spot". If evolution is right, then we should find our planet's orbit "sweet" (after all, those who found it harsh would have been weeded out, leaving those of us who love it here!).
The whole numbers game is ridiculous, as it's like saying nobody could possibly win the lottery since it's so unlikely...yet people do, since there are so many chances! How many billions and billions of planets are out there?
