Alien Life

[Phoenix-D]

"I have to be honest, I do not believe in life beyond this planet. I would like to believe, but I have come to realize that we have no idea how old the Universe really is, or for that matter, how large. It took me years to come to understand that the Universe if infinte, that it really has no end. And because of its massive un-ending size, if there is life other than us out there, we will never ever see it. The distances are too great to pass.

Oh sure eventually our scientist will invent things that will make traveling the stars possible, but not for another 100 or more years.

"I once felt that life was out there, and that they had visited Earth. But it has been proven that no one can keep a secret, espeically one as large as finding a UFO. Our planet is so delicate and rare in its make up and formation of atmosphere that a second planet like Earth would be so rare that it can not be calculated by our current mathmatical abilities."

Not exactly. Low chance doesn't mean much considering the *size* of the universe, and it's age.

Let's say that there is, per star, a one billion to one chance of life- ANY life- developing.

The estimated size of the Milky Way- that is, just our galaxy- is around 200 billion stars. That's *200* life-bearing worlds if the statistics are correct. In just one galaxy. And I think this is a bit low myself, though there's only one way to find out. Go look!

"Closed minded, no. Facts are facts. If Earth was not a rarity, then why do we not have other inhabitable worlds in this solor system?"

Perhaps because there are only 9, and of those only one or two are in the liquid-water zone? That and we haven't explored the entirety of our solar system yet. Life pops up in odd places sometimes (hydrothermal vents are the most promising)
