I've always wondered what life in space would be like...
Space is a huge dimension of nothingness.  I can't really comprehend it yet.  Do you think there are aliens in space?
I don't think there is aliens in space. However, I do believe that because there are so many galaxies, there's so much unknown yet to be discovered.
I agree.  I've just watched Infinity War and it seems like there could be many different forms of life we are not aware of.
Interesting, I never thought about the different forms of life.
With the Infinity War movie that came out, the Avengers join forces with the Guardians of the Galaxy.  That right there is an example of different life forms. 
I haven't seen that movie yet but I'm aware of the Guardians of the Galaxy. Interesting to think of life on different planets for movies.
I'm just using the Marvel Cinematic Universe as an example.  But even within the MCU, it's based on characters from all over the universe.
