If you could walk the circumference of a very large sphere, it too would appear to go on forever..... By the time you got back around, it would not be the same thing again :2cents:That is like an infinite loop, when does it gonna end :laughing. Too much space to deal with, I will just stay here and enjoy doing wheelies on my gixxer .
There statistically was at some point. But the likely hood of aliens landing on front lawn of the White-house is remote. Even if you assume Man will live the same range as the dinosaurs ie. 60 million years. That time frame is small compared to the roughly 14 billion years the universe has been around. (According to Big Bang) So two species, at an intelligent level, at the same time is remote.gotta be aliens somewhere in there
