The Milky Way galaxy to me feels like it’s ours now whatever happened in the past, greater civilizations probably have picked a galaxy and colonized it rather than be spread around different galaxies unless for industry. There could be some federation or government like our NATO which they stick too what makes earth untouchable like the people of sentinel island
the milky way is not ours, much like this planet is not ours. we inhabit the planet, the milky way, and the universe alongside the other things which live here with us. nothing is ours to conquer, and that is where our ancestors went wrong. nearly all of the woes that plague our society today trace back to european and capitalist conquest
