you asked why aliens would come to earth well if they are as advanced as every body says they are wouldnt it be the same thing for them to travel to another planet as it would for us to go to maybe russia or spain or any other country? and you tell us to think before we post a comment when u act like that aliens (if they are real) dont have a mind to think for them selfs i mean even our rats have a mind to think for them selfs. thing is that what they do isnt some thing to question but accept. if they go out and think they want to travel here is the same thing as if u walked out you’r door and walked to the gym or something.
