believing in life on other planets is completly different from believing they have visited us. I think it's entirely possible there is life out there but with out any hard evidence I don't believe they have been here.

I have even had an alien encounter and choose to believe it must have been in my head because there was no evidence of it the next day and no other witnesses. I have seen ghosts too and I don't believe in them either

my point is I can see no reason why aliens would visit us all these years without leaving some good evidence about it other than human experience. The human mind is very complex and will trick us easily.
