While we're on the subject of heat etc., the moon's varying temperatures would make stable life almost impossible.
Beacause there is very little atmosphere, and the surface of the moon does not hold heat well, the air temperature on the side away from the sun - the lunar "night" or "winter" - is about -88C (surface temp. -193C). This rockets to 58C (surface temp. 111C) in the lunar "afternoon" or "summer".
This varied climate would probably put paid to any water-based life, which covers life as we know it, so the prospect of life on the moon is rather dim.
