Lol. People like that are funny. I'm a Christian and I don't have a problem with there being life on other planets.

With the vastness of just our observable universe we can see. The odds of earth being the only planet with life is just unreasonably small. Even if it's just single celled organisms.

Well, what are the odds of life even arising in the first place? The conditions had to be pretty perfect for life to arise on Earth, and that can't just be a common occurrence for those conditions to line up as they have, can it? What is extraterrestrial life was hostile, and killed itself? What if we are incapable of perceiving them? What if there [i]is[/i] extraterrestrial life, but we are the only lifeforms capable of intelligence? Too many variables, too many unknowns. There's still so much we're just not sure about the inorganic universe itself. Perhaps we're leading ourselves astray with visions of extraterrestrial life that could give us all the answers.

We need to free ourselves from the thought process of any life has to be exectally like life on earth. Or that live only come from the conditions that we need here on earth to have life. Heck I believe that there are non carbon based life forms out there as well.
