Is there life on other planets?

Is there life on other planets?Some people think this is not possible,but I think it is.I can't believe that we're alone in this big universe.Now,I'll explain why.
First of all,many earthlike planets have been found throughout the universe,Mars being the 1st planet where the scientists have found water,containing micro-bacteria,which was the fundamental element for life on Earth. What is more,there have been recordings of strange and even supernatural things happening: one summer,2008,in Mexico,N.A.S.A. found an extraterestrial being,whose DNA couldn't be read,because of its complexity.Also the farmers,who deported the creature to N.A.S.A. said that there were some lights and a strange sound,which made the dogs bark.The ,,spaceship'' wasn't found,or this is what N.A.S.A. declared.Perhaps they're still analyzing and trying to decipher its secrets,even nowadays,but didn't want to frighten the world about the findings on it.
However,the galaxy is so huge,that there may be other planets,not in our Solar system,but others,where life is better,leaded by higher technology than ours.
The points I've mentioned don't really prove that there's life on other planets.But I'm sure one day man will be able that there i some form of life in places like Mars,becasue it's the nearest planet to us and it'd be the 1st one where people would live.
