Illegals don’t count. ;-) This is exactly what the Fermi Paradox is about. If there are sapient aliens, where in the heck are they? Go read about it a bit. It more or less supports your contentions.
I know. I knew Fermi. Fermi was a friend of mine. He wasn’t outrageous like Feinmann. I have no contentions and this is all very old stuff.
