Because of the distances and energies involved. The Fermi Paradox is pure codswallop IMHO.

I take it then that you don't believe humankind can ever explore another solar system. (because if we can then it is a process of time and reproduction etc....)

I did not say that. What I said was that the Fermi Paradox does not correlate to the possibility of life out there. It only addresses that they are not here. So when I hear that we are alone in the universe because the Fermi Paradox says so, my reply is codswallop.
