Spartacus,
Your comment: I say again, it is arrogant to believe that we humans are the only intelligent beings in the universe and in our galaxy. To thinks so runs blatantly against logic.
Yes . . I too . . . believe that it would be presumptous on our part to think we are the only intelligent beings in the universe. Furthermore, our human intelligence is relative. We may be quite primitive compared to life in another galaxy.
