life outside of earth?

yes, i belive there is life outside oof our atmosphere because what are the chances that there is only one place in this whole universe that has life. i belive that there are millions of differant galexy's just like ours that has nine planets and has some of the planets that can have life. i dont belive that, that was a ufo because i think that they might have stopped or sent a signal if it was a ufo. do you think that there is life outside of our galexy?..
