YES... they are watching you right now...

I think there is a lot of evidence of Aliens visiting this planet in the past. If you study history, there are so many unexplained mysteries that man could not have possibly known at the time with the lack of technology they had. Things like mapping of the stars, or mapping of the lands and geometry. Read about the Mayans and their predictions. They have an intimate knowledge of the stars, and it puzzles everyone still on how they knew.
