Hi,

I agree with you. I am a fan of the Weak Anthropic Principle, which can be expressed as saying we should not be surprised that we are here. It is not that conditions fit us perfectly, but the other way about.

We already know there is enormous variety in the Universe, so, here and there, such conditions will occur. However the distance between such places would mostly be vast I believe. This would act as a natural quarantine (as far as we know now ).

This goes to address Fermi's Paradox ("where are all the aliens?"):
