Do aliens really exist? Is life outside of Earth real? Answers to these questions I may never know. In my opinion, it is very likely that life goes beyond just our planet. I think that there are many planets that are almost just like Earth. Although those planets might not be inhabited by green creatures with 3 fingers, there may be some form of life, like small insects, that live in that planet. I do think that in order for us to survive, we need water. I believe that on other planets, water does exist. Hopefully one day, us "earthlings" can discover these planets and maybe even live on them.
