But Homo Sapiens hasn't made it past the predatory stage of development, addicted to war, violence, domination. Most groups with the power tries to dominate those around them. (Always in the name of "defense".)

I suspect that until and if we get past the point where we are fighting each other information from other civilizations will be scant.

First, contact will probably take a civilization which is not devoting most of it's resources to destroying parts of itself and can devote them to it's people, their education and scientific works. Only they could have generated the knowledge and techniques to reach across a galaxy.

Second, I doubt those intelligences would have an interest in contact with a world which is still basically predatory and hasn't moved on to cooperation and respect.
