When you look up at the night sky it is littered with stars. Each one of those stars is or was a sun. Each sun represents a possibility for a solar system due to it's gravitational pull and size. Each solar system represents a possibility for life. Taking into consideration that our sun is one of the smallest stars in the sky, other larger suns would have a larger "sweet spot" where planets can orbit around their sun in temperatures that would allow life to exist. Each solar system has their own table of elements, recently discovered that some known solar systems have almost double our elements.
Therefore, If there is a star in the sky that has a solar system, and this solar system contained the correct elements located inside a rock that orbits that sun, and that rock is the perfect distance away from the sun than it is stupid to assume that life does not exist there. In fact, I will bet down to my last penny I ever make in my life that life exists somewhere other than earth. But that does not mean it's intelligent life. Life in other parts of the universe could mean that algae is floating in a body of water on some planet.

Comments: Yes aliens do exist , because if we as human beings find something to be unfamiliar then we would call it alien. This planet was natured by other forms of energy including alien forms of energy.
Throughout this earths history we as humans have been monitored, why - because like a child growing up you need to keep an eye on them and possibly guide them through the path.
Mankind is so full of itself that even if we did come face to face with et , our first thought would be to conquer ( the being and the intelligence around the being ) .
Governments already know aliens were on this planet long ago, in fact this planet, pronounced arth is very symbolic to various alien beings ( by the way there are over 60000000 alien beings in this galaxy alone ) they use this planet like a service station and the galactic map says you can go through earths atmosphere but if you stop and ask for directions from any of its civilization( be warned your on your own ) p.s aliens like to come here to charge there vessels as well ( occasionally take the scenic route , through our storm energies.
They also send orbs ( or drone type vessels ) just to monitor the situation and the beings on this planet.
P.s they also think we are one hell of a crazy species that we are in fact exempt from joining the galactic federation ( at least until 2070 ) . or until mankind reaches a higher level of being( enlightenment ) - so my bet is on 2070 - and even thats not 100 percent . Still we are into the age of Aquarius lets see what happens.. Et might come back only this time he will have a Motorola star-phone
Ha! This one is easy yet complex and scary for me, personally I have no doubts that there is other life out there because I mean, look at that the NASA has just discovered a system with 7 planets that could have life in them! Unless of course you're a conspiracy theory nerd and think that the system doesn't exist .
