Addressing point 2, I'm pretty sure there's other life forms in the universe. What I saw wasn't anything that has been known to exist here.
Adsressing point 3, mathmatics does not require it. I remember seeing the formula somewhere, something like P = S*E*W*L. P is probability life will arise. S is the probability that there are planets around a star. E is the probability there's an Earth-like planet there, in terms of a planet exisiting in the star's habitable belt of temperature range. W is the probability that liquid water will exist on siad planet. L is the probability that life will arise under optimal conditions. The point is that we don't have values for any of these. As such, it is easy to estimate values that would make it seem that almost every other star has a solar system half of which has an Earth-type planet, and every solar system that has an Earth-type planet with water will make life. It's just as easy to estimate values that would make it seem that life is almost certain not to arise, leading to an extremely small handful of life-bearing planets in the universe. I guess the point I'm trying to make is that we really cant say that mathmatics proves that extraterrestrial life must exist, but mathmatics also can not say that extraterrestrial life can't exist.
Hah, nice. I believe the lecturer I have for my cells and genes unit did some work as a marine biologist. He was very enthusiastic when he gave a lecture on protists.
