If they had seen the internet they would have seen all the scientific collaboration and perhaps found it reason enough not to judge. Maybe the aliens want to fuck some humans, too, for all we know. That's how we came out the way we did if you ascribe to the ancient astronaut hypothesis. Anyways, you guys are assuming a lot about alien psychology when our sample size of intelligent species is one, which in scientific terms is woefully insufficient to make definitive claims. I'd like to remind everyone that this is all highly speculative and just for fun.
