Actual Infinities

[Mudhammam]

That sounds like a bunch of fine-tuning nonsense. Life is as simple as geometry, actually; and despite the claims of the Creationists, probably driven by entropy. As for intelligent life, it seems the only chance that we are alone is that if we're first. 

There is a fairly broad consensus that are our universe is fine-tuned for the environment and building blocks required for life. There are various explanations as to why it has these specific characteristics, which if tinkered with ever so slightly, would have made life as we know it impossible. Make of that as you will. My only point about the near guarantee of life existing elsewhere is that any such assertion is purely speculative.
