I have often thought that Earth is so unique, it harbours the only life in the universe! Everything had to be JUST right for life to first take a hold.
A denser atmosphere --> No life (Venus)
Too hot --> no life (Mercury)
Too little atmosphere --> No life (mars)
to name only three amazing co-incidences that have to be met.
So, do you believe Earth is the only life harbouring place in the universe? Is the odds of this accident happening again less than the number of stars with planets?
So far, we have not even found solid evidence of even a single celled form of life in the few places we have managed to explore and received no convincing signals from space (except the 'wow' signal SETI found but that could be natural).
