You gotta think of it this way, though. First, they kept making the argument that if the earth was like a mile off its orbit then life as we know it would seize to exist. Then they made the argument that planets are a rare thing and that our solar system might be the only one in the cosmos with planets. And then when they found extrasolar planets, they made the argument that rocky planets in habitable zones are extremely rare such that earth could have only existed because god created it this way.
You see where I'm going with this? They keep moving their goal post. Now that we've found hundreds of planets in habitable zones, I'm just hoping that they could finally shut the hell up.
I am convinced that eventually we will find out without a doubt that the universe is teeming with oases of habitable conditions for life.
What's the difference between my belief in this and the christian faith? Well, for one thing I don't care if other people believe this with me or not. But more importantly, I don't flood internet forums with my bullshit.
