Natural

Well, here we are. This is, more or less, my first real post on what will inevitably become something so trivial that it becomes of utmost importance. And, I suppose, as a first post, it is only customary that it is used as an opportunity for us to get to know each other. Unfortunately (or, fortunately, depending on your personal hygiene), this is a very one-way medium of communication. So we will throw that idea out sans hesitation. So, to set the pace of all publishings to come, we will start with some philosophy.

Inevitability:
First, and foremost, please erase from your head any ideas you gained from The Matrix. This is hardly the place for such things...
Here, we are referring to the inevitability of life. A lot of people will credit the existence of life on this planet as the work of some sort of god, deity, or magic pinball machine -- in short, something that put us here, evolution and all that fun stuff aside. In all reality, it makes much more sense that not only could life just come about on its own, but it had to! Let's agree right now that the universe as we know it, for all intensive purposes, is infinitely large. And science has shown, rather conclusively, that the basic building blocks of life can be created in an aqueous environment with minimal molecular ingredients (like hydrogen and oxygen, which both exist naturally anywhere they can) and an electrical catalyst (like a lightning storm, also naturally occurring).
Now, keep this in mind. Infinite size allows for complete possibility. Imagine flipping a coin. 50% heads, 50% tails. Now, what are the odds of two heads in a row? Three? Ten? The more in a row we need, the lower the odds of getting it. BUT, if you could flip the coin an infinite number of times, what would be the odds of, at some point, getting two heads in row? Three? Ten? A thousand? The answer is 100%. Pure and simple. Flipping a coin forever will eventually produce any result desired somewhere along the line (with, of course, the exception of infinite in-a-rows).
So, in a universe of infinite size, which must therefore have an infinite number of stars, solar systems, and yes, even planets, must - somewhere along the line - have a planet (as rare as it may be) that is just right for supporting life. In fact, it must have an infinite number of these planets.
It is somewhat like saying, "the odds of a planet like earth, capable of supporting life, existing - with how specific so many factors must be - are the same odds as flipping a coin to heads ten million times in a row." Though it seems impossible to happen by chance, remember that when dealing with infinite possibilities, not only can exceedingly rare things take place, they must.

So all of this is intertwined with a lot of different philosophies and junk, and even goes on to infinite universes and string theory, but I thought it was important to get down. Next time will be funny, I promise.
