i got a theory.
when you see a bug. A fly or ant or spider. What do you do. Kill it right? well, this is because humans are so used to being dominant, we kill the smaller, because we can. When we see a bug we go "EEEWWWW!" and try to kill it. What if aliens, that are much more advanced then use, find us and go "EEEWWWWW!" and then try to kill us? because we are inferior to them.
