Aliens

I believe that aliens can exist in our universe and I think that they do. It seems a little odd that out of how many galaxies we are the only planet that has life on it. Experts don't think that aliens exist because we haven't ever communicated with them, but maybe they don't know we are here. If they do or don't, they might not have any desire to interact with us of to find anything out there like them. We might not ever be able to reach a distant planet that could support life just like earth, but that doesn't change the possibility that something might be out there. Another side that no one has considered is what if there is another form of humans out there that doesn't need the same elements to survive that we do. When we explore Mars, we look for water or things like that but there might be another form of people that don't need things like that.
