Too bad you can't talk to Isaac Asimov, who was a professor of biochemistry at Boston University. He calculated on the basis of the size of the universe, it was unlikely there were other life forms, based in the narrow spectrum that life filled on earth.
It's been estimated that there are somewhere in the neighborhood of something like 40 billion possible planets which have something called a circumstellar habitable zone (a/k/a/ the "Goldilocks zone"), the region around a star where a planet with sufficient atmospheric pressure can maintain liquid water on its surface. In addition, something like 11 billion of these likely revolve around a star similar to our sun.
While there are certainly a slew of other factors to take into consideration other than just the presence of water and and an atmosphere similar to earth's, the sheer number of possibilities alone make it, at least for me, virtually impossible to believe we're the only ones 'out there'.
It's a bit difficult to wrap one's mind around how utterly insignificant our little spec of the universe is. And yes, one could certainly argue that the Creator of the Universe itself decided to pick our insignificant spec, but religion aside, who's to say that said Creator hasn't done exactly the same everywhere else?
Absolutely no offense intended to anyone, but looking for evidence/suggestions, etc. of extraterrestrial life in the Bible is a bit like looking for evidence of cell phone usage in the Bible - it just isn't there; why would you ever think it would be?
