Have you thanked the moon today?

Finally got to watch "Fly Me To The Moon" from the CBC's Doc Zone. I might have heard this before and forgotten, but was struck by a brief mention that our beautiful moon was quite possibly instrumental to life arising (and surviving) on Earth. And what are the chances you're going to have a huge satellite (huge relative to your planet) orbiting you, along with all the other conditions necessary for life? Not very good according to the Rare Earth hypothesis - check it out on Wikipedia here. Helps explain the Fermi paradox. Gotta love the people that use information like this to argue that there has to be an 'intelligent creator' out there. If we didn't happen to have just the perfect conditions to be here - we wouldn't be here asking these questions :) Also the universe is huge - it's simply a numbers game. So who knows, maybe we are the only game in town?
