I think its pretty foolish to think we are the only life forms in the entire universe

I am unsure if any said life form has visited earth tho. I know there are tons of limitations that many argue make it impossible, but I also know we dont know all there is to know, so I definately think it could be possible. Im undecided tho, It wouldnt suprise me if it had happened, but I think pretty much all "crop circles" and "ufo sightings" and "governement coverups" are bogus. I think if aliens did come to earth, theyd have the technology to make it so that we never saw them.
