We're not full of crap...

...about the amazing fine-tunedness of our planet for intelligent life. We're not crazy religious people just making this up.

So claims this recent article at SPACE.com (without reference to the religious stuff).

Earth has liquid water in the just-right amounts, plate tectonics, a large moon, etc., all of which are necessary for the existence of advanced, intelligent life.

Donald Brownlee of the University of Washington debunks the silly speculation regarding the existence of life elsewhere in the solar system:

"You hear all the time how Earth-like Mars is, but if you were taken to Mars you wouldn't feel happy there at all," said University of Washington astronomer Don Brownlee, author of the book "Rare Earth" (Springer, 2003). "It's not Earth-like. And Titan, when the [Huygens] probe landed, there was all this stuff in the media about how Earth-like it is. Earth-like? It is completely different. It has all this methane on the surface. Venus has about the same mass [as Earth], almost the same distance from the sun. But it's a totally different place — no oceans, no plate tectonics — and it's not a place you would want to be."

So far, we haven't seen any planet outside the solar system come very close to Earth either.

Of the nearly 300 new worlds glimpsed elsewhere in the galaxy, most are "hot Jupiters" — large planets that orbit close to their stars, on which life and liquid water are unlikely to exist.

"I doubt that in our galaxy typical stars have planets just like Earth around them," Brownlee said. "I'm sure there are lots of planets in the galaxy that are somewhat similar to Earth, but the idea that this is a typical planet is nonsensical."

This is where the real science is going. And it's teaching us lots of things and making astronomy more exciting.
