Stephen Hawking says Aliens exist...do you believe that Aliens exist?

i do believe they exists as birds existed in our world.. i think we are not alone in this universe, because of the vastness of space, who can tell that we are the only living creatures existed..

In my perception Aliens do exist. It may not be in the form which was given by Spielberg or Lucas in their movies, but they definitely exist. Atleast in the neighbouring Galaxy :P

This is my opinion: We didn't take birth in some other part of the universe, came in search of a planet suitable for life, find earth and then settle here. We were created according to the earth's environment. As we know, each and every creature in this planet is evolving to new dimensions according to its surroundings. So, life is created in such a way that it suits the prevailing environment. Same way, life may be created in other planets too, based on their climatic conditions. So there is no point is saying that 'Earth is the only planet suitable for life' and 'Aliens donot exist'! Here my discussion regarding this... http://www.mylot.com/w/discussions/2310666.aspx

it is very possible that aliens do exist there's like a billion stars and a billion billion planets out there. with that large number of planets out there, earth can't the only one that supports intelligent life.. plus, according to Star Trek, after earth has it's big war (which may happen in our lifetime), somebody will invent an engine that can enable us to travel faster than light (warp speed). and then the Vulcan's (Mr.Spock's race) will come to earth to say hi.. so we just need to invent that engine and they'll come to us
