I can’t say I know a ton about space travel and how realistic life in space would be, but here’s my two cents: I think expanding our horizons and colonizing places like Mars or living on a space station would have some benefits, like additional space on Earth and additional research possibilities. NASA recently announced that they found water on the moon, as well as on Mars a few years back, showing how new things are being discovered about the universe all the time. However, I think we still have a lot of time to go before life in space is truly feasible. However, I think there we may see some major developments in due time.
