I am going to guess you aren't much of a Star Trek fan. If early human beings had your philosophy, humans would be a tribe of a couple of hundred people still hunting and gathering in Africa.
Humans evolved to be explorers, developers, and builders. I like us that way.
Don't worry, it is a big Universe. It is Ok if we poke around for a bit.
