José Carvalho asked Neil deGrasse Tyson:

When we'll encounter other alien rational life forms, what would be the defining characteristic of humankind? Would we be the social one? The species that relies on vision? The most fragile?

Neil deGrasse Tyson We will be the blithering idiots of the galaxy. Intelligent aliens that visit Earth will will wild technology far more advanced than anything we're capable of. They will see one species of life on Earth, that drew lines on the land, with rules that prevent people from crossing those lines. They will see one species of life that is prone to subjugate or kill other members of its own species simply for who they worship, who they sleep with, or what skin color they have. These are all signs of the absence of intelligent life on Earth.
