exactly, now compound from that, or extrapolate from that, technology. look how rare tech is on our own planet? just in the last 150 years, maybe, less even, in the billions of years we have been here! and we've only figured out how to get 238,000 miles out, and i am factoring in politics and money too, an evolved alien race with the tech to get here certainly has politics and resources to consider as well. that's not just a human condition.
