But there are also areas which are even more stable. If you look at the odd areas life is found in on the Earth, it is clear that something will fit any niche. Our niche is almost ideal from our point of view because we have evolved to fit it. This indicates nothing special...in my atheist opinion - we have seen the smallest fraction of our galaxy, let alone the universe, so what can we say about life elsewhere, other than the likelihood of some type of life filling a niche is high because we are here and space is big...very very big.
