..and, of course, my thoughts are along the lines of: Well, they're probably way more advanced than us and probably have known about us for a long time.. and they haven't gone out of their way to holler at us - as far as we know, anyways.. They could have cavorted with the ancient Egyptians or crash landed in Roswell in the 50's..
Point is, apparently they don't necessarily want anything to do with us PUBLICLY, so why poke the bear? They may come back and do a sequel to Independence Day for real.. Even if we tried to contact them and sent a super awesome signal to them, we'd probably be dead before it got to them - more than likely dead for sure before they responded..
I'm a firm believer in life on other planets.. maybe not a LOT of life, but life, none-the-less.. But, until you know who you're dealing with, don't go running off the greet them with a laurel and hearty wreath....
Friendship is like peeing your pants.. Everybody can see it, but only you can feel the warmth..
