ONCE AGAIN ???
The scientific fact that humans are limited with their current space travel could be that they are looked upon as something not ready to be propagated within any distant areas as of yet? All one need do is 'Ask an Indian' ... Wasn't one Columbus enough to prove that? ... Humans also need to realize that their brain functions come with limits just like the calculus of everything else on this planet ... Looking at other animals, knowing their brains have limits should be proof of that also? ... Enjoy the ride ... TEd ...
