Theories and the History Channel

So I think science is funny. We've been watching the History Channel and the theories of how the Earth and Moon were formed are hilarious. Not that I have a better explanation than God created them, but the fact is, these theories are really out there. I guess because I have my faith in the Lord that it doesn't cause me to look around and think, now how did that get there? I don't think it is blind faith, but I feel nothing I've heard has felt to ring true like my accepting that God created it, and it was just there. :)

Anyway, the theory of the oceans forming on the earth is that after a big meteor hit the earth, it was cloudy, therefore it rained for millions, and millions, and millions of years (remember the Earth is BILLIONS of years old), so raining for millions of years straight is nothing in the drop of time. Then the moon was formed by astroids/meteors hitting the Earth hard and a piece of Earth breaking off, and then the earth got back into a round shape and the moon went into a round shape and supposedly just stays in orbit around our Earth perfectly and helps with the tides of our oceans and forms our calendar as well. First it just makes me ask, why aren't we getting hit by anything lately? I feel like they keep leaving that out. And second, everything is just too perfect and orderly for me to accept these theories.
