Aliens! e_e

I think its ignorant to think that there is not life in outer space! Of course there is. I mean think of the Great Pyramid or of Stonehenge, how could people do that without any abnormal help? They did not have half of the things we have today and yet they were able to create these things. You can't tell me people were alone in doing that. As for invasion, i believe it is already happening and has been happening for centurys.
And honestly, i don't understand people who take the time to match their socks. They're socks, no one sees them. O_o
