Other positive things to mention about space exploration:

• If humanity spreads out across the stars, there is less of a danger for us dying from ANY centralized disaster including the cosmic ones and those we might cause ourselves
• Similar to the above, it will be harder to create centralized governments due to extreme distances and just communication limits set by the speed of light; ergo, if some colony falls prey to a dictatorship it is unlikely to spread easily across all of humanity
• We have lots of questions about the universe which may be answered if we travel it. And, when scientific discoveries are made they often have applications outside their initial field.
• We have lots of questions about biology that living in novel environments would teach us (also lots of other scientific fields too of course)
• Forming colonies will force many small groups of people to work collectively, causing those colonies to form a sense of community—something that is lacking in humanity presently
• Isolation caused by communication limits will be scary but also will decrease our access to 24/7 terrible non-local news (inhibiting our ability to doomscroll) which will likely have a positive impact on everyone’s mental health (..maybe not on earth but in the colonies at least)
• Exploration becoming a possibility will also likely make people happier just by showing that humanity has a future. Also, knowing that there are places you can go to escape society all together is quite a freeing thought for some
• Last but not least WE GET TO GO TO SPACE!
