Being alone in this huge and huge universe is creepy, fun and lucky. But are we alone? It is very unlikely that we are alone because there are hundreds of billions of stars and each stars have their own planets, sometimes a single star have 1000's of planets. And life may exist in many forms. It is not a compulsion that life is like in earth everywhere. Maybe somewhere in the universe life is in gaseous state and somewhere may be living in stars and life may be fire or so.

Proof of Aliens

Not talking about all those lame theories like wow signal and other false and unproved signal we got or they rumored for getting that, just think about the possibilities of life. Mars, which is our nearest planet have sign of life and we haven't even explored it yet. After a search of just 50 years we got a planet 10 light years away which have a very very similar property of that of earth. It is almost sure that life can be possible there and a spaceship is already launched in 1983 and it will take around 16,000 years to reach there. There are billions and billions of possibilities, they be also be searching for us. If the evolutionary pattern is same then there may even be thousands of people exactly similar to you, exactly reading this same article and exactly upvoting and resteeming this same post after sometime(Kidding).
Aliens may be destructive as shown in many movies or aliens are controlling us and had created us just for fun. There are many many possibility.
I personally think aliens do exists and Stephen Hawing and other Scientist also think the same, but it is always your choice to believe it or not,

So.......
