"Aliens do not talk to us just as we do not talk to ants or calculus to our cats" This just made me think about this : if they would talk or if they're already do it, we cannot discern their message from what is already within our knowledge therefore we cannot recognize them as aliens.  Remember,  the cat thinks we are ajust a bigger cat. The ants not even close to that. But then aren't we coming  in full circle with what we call mythology,  superstition and religion?
