Cool video, but he neglected to mention how inhospitable the universe can be. If your planet is getting hit by a GRB every so often, life won't have the time it needs to really get going.

Argh. I hate it when people say that it "required" a very specialized set of conditions for life to arise on Earth. Instead, I would argue that life on Earth arose in a set of specialized conditions and is therefore accustomed to those conditions.

Life similar to what we have seen on Earth might "require" those conditions, but why should we assume that those conditions are required for life in general? We have discovered life here on Earth that falls outside of the hospitable conditions that we have previously thought of as being "required" for life. For example, consider extremeophiles like the organisms that live around deep ocean vents, and can survive and thrive in water well over the boiling point, with no sunlight, etc.

There is a limited range of conditions present in Earth environments; a maximum and minimum temperature likely to be encountered on Earth, varying amounts of light or other sources of energy, etc., and we can find life adapted to wildly varying positions within that range. Why do we continue to assume that Earth-like conditions are some sort of magic combination for life? For life "as we know it", ...maybe. But I figure there is a probably a lot of stuff out there that we would recognize as alive, but which is adapted to very different conditions than anything considered hospitable to any life on Earth.

Those people have been programmed with the fine tuned universe argument. in fact,the opposite is true. Life grows where it can,the water always thinks the glass was made just for it.
