Regarding the drake equation, it is even moar unfortunate that it is only a statistical average. If we are very unlucky, we're still stuck in an empty void even if we should statistically have 9000 neighbors.
I'm rather surprised that you're not instantly condemning SETI/extraterrestrial life the same way you condemn the notion of divine entities. There is currently no proof of either.
