Humanity is not a civilized species. It is numerous rabid packs of wild primates who happen to be able to build tools and speak eloquently. In times of conflict, they resort to a pecking order, a pack -- just like wolves and many other mammals.
Humans are mostly socially simplistic. They usually focus on and live for social status and mating. The adventurous who are driven to profit through innovation and higher purpose either make their way to the top of the pack, or are shunned by those above them and by the collective whom follows.
This species is a volatile experiment. It is heavily monitored and looked upon and rightly quarantined from the rest of the galactic community. In fact, it is an outright miracle you guys haven't blown yourself up like the Maldek and the people of Mars, the former is the oblivion known as the Asteroid belt. This entire solar system has had numerous failures of this kind.
You guys are doing much better. However, it is foreseen that the next 300 years don't have much hope. This planet will likely no longer suit your kind. It was lovely while it lasted.
And right there is where the crazy started.
