The enormous age of the universe means that even if many civilizations flourished for a million years each, very few of them would be contemporaries. It's a harsh universe and surviving for a million years would be quite a feat, even if they didn't have humankind's self-destructive tendencies.<br /><br />2.

Electromagnetic signals would be undetectably weak beyond neighboring stars unless they used a significant fraction of their star's power. <br /><br />3.
