So far we've been to the Moon,sent a probe or two to planets (and moons) in our solar system and only peeked from a rather large distance at other planets....some of which I believe we can only see by the effect they have on their stars.
I think we can be a little more confident of life ;-)


Hi Goldy. We haven't seen anything that is inconsistent with earth being the only place in the universe in which life has evolved. I agree some of the data is good as planets seem common and presumably earth like planets are also common. But maybe planets are common but life is extremely rare. I don't think we know enough about the numbers yet.
