I still don't know where I stand on this. I feel like there are still too many variables remaining. Surely it confirms the notion that life-bearing planets similar to Earth could be common, but I'm uncomfortable taking it much further than that.
I see it as confirmation that the universe has many opportunities for life to arise, not just one special case situation.
I put this together with the fact that pre-biotic molecules are common in space (see [tidm=296041]Building Blocks of Life[/tidm] for some of the evidence) and conclude that the formation and subsequent elevation of life is hardly impossible.
