Do You Think There Are Extraterrestrial Civilizations in the Universe?

i always hope it might be aliens, but i don't have very high hopes. universe is so big that it almost seems inevitable that there must be some kind of life out there. I think given the size of the universe, it seems fairly likely that some kind of civilization has arisen. And something that convinces me as well is that we have all these vidios, but they are all of totally different kinds of apparent phenomena. It's all just one big detective story.
