I was thinking along the lines of,thats the key to all this,what is life and how the uniwatsit created it all from as you say, micromebia and the likes.

Pete put life then us and I agree (dont think pete meant it same as me however) we want answers ,nothing else cares. How many species ? why all on one planet ? why have a lifeform trying figure it all out ?,whats everything else doing? lol

So life and then us makes perfect sense to me as we will work it out on how to populate a planet 🙂 very odd this evolution malarkey.
