Do Aliens Exist? 
I feel as though this question has been circaling around up in the air for quite sometime. Scenetists have been studying this topic for a a far amount of time. Theres always questions feeding off this one question. Questons like "If they exist, will they kill us" or "Whata re they and what do they want if they ever came to earth". I cant help but feeling as though this question of if aliens do exist is jsut so we can have something to fear or question. Has an alien siting ever happened? Some people say theyve seen aliens, some  people believe that aliens are not real and havent ever vistied earth. But then again its all waht you believe in. There has been no documented record of alines visting earth, but who knows. Whos knows if aliens even exist, who knows even if its possible for aliens to exist. I do know that they have found organisms on Mars, like the begining of life forms growing. But they question of them being alien is yet to be known. Just because we think that there might be aliens forms doesnt mean that they actually are aliens. These life forms on Mars are in question though.  Theres nothing more interesting and kind of scary to have the thought of aliens lingering in the back of your head but its one thing to believe it and one thing for it to actually be real and seen not jsut said though word of mouth. Aliens do interest me but then the thought of them actually being real is kind of  erry thought.
