Well, you are wrong, but allow me to point something out to you: water vapor is....water. So, what? You're contention is that it's somehow a problem that all that water came from all that water?
But, he typed magnanimously, here's the quick version: when an oxygen really likes a hydrogen molecule, it'll get up all close like and then the hydrogens will extend valence electrons towards the oxygen's special orbital place and they make sweet, sweet covalent love. So anyway, this happened about a gajillion-trillion times in the solar system of uber-yore, like way before Earth even formed and so it was right there for the taking and Earth was all like "Dude, gotta get me some of that." And it did, with its amazing gravity superpowers. Oh, and some comets and other stuff with even more water kept falling onto the planet. It was sort of fad there for awhile.

Same way everything does? You know, losing heat because it was, like, way warmer than outer space and stuff? Thermodynamics, entropy...ringing any bells yet?

Well, um, the water vapor mostly turned into that lame "liquid" water stuff, whatever that's all about. Tends to do that once it cools. I think that thermodynamics crap is involved somehow. Seems like it's got its fingers in everything. But whatever...
So, OK, like a lot of CO2 got broken down (by The Man, of course). The carbon, which you may have noticed is prone to forming all that biochemical stuff, eventually formed a bunch of biochemical stuff. Plus some of the less fortunate atoms got mixed-up with mineral and other inorganic manufacturing cartels ( I don't want to talk about the poor bastards that radioactively decayed. Too fucking sad, man. Not goin' there). The O2 went solo (or I guess duo) and just sort of roamed the atmosphere, gathering numbers and waiting for when the time was right to strike. Or rather, when the time was right start getting consumed in all sorts of newfangled biochemical reactions. Some CO2 managed to escape this chemical doom and went on the lam, hiding in the oceans and suchlike. Similar epic sagas can be recited for other components of the early atmosphere. Hey, I just had an idea: try looking this stuff up, man. I would totally bet someone's looked into this already. Anyway, all this water talk's got me thirsty....
