This is my loudest bork
Earth...........is fine. No insane world-ending apocalypse like robot uprising movies or earth becoming unlivable like in Wall-E, and no nuclear war or zombie uprising. Humanity wisened up and prevented all that before it started. With insanely advanced technology, robots can be made to be sentient but disconnected from other robots. There's no AI Hivemind that makes every robot a killer. Androids and sentient AI are specially made with extreme regulation and care, the programming only to be made by human hands to prevent a mass malfunction of androids. Some robots can go about committing crime, but at the end of the day, it's no different than a human committing a crime. Pollution has been solved with one of many alternative ways to produce energy and alternate fuel methods, though gas in general is pretty outdated. The Ozone is perfect again, the earth environment preserved and recovered due to humans colonizing many other planets
Humanity lives in harmony with other races. Any alien species that tried to take over earth was beaten into submission and then made to see the error of their ways. Interstellar trade routes established. Outerspecies and human/AI relationships normalized (though reproduction is impossible obviously).
With galaxies far and wide, it's a huge universe to explore. Not every species knows about humanity or they may not like humanity. Some species are sitting behind a computer releasing videos to their own version of the internet talking about how they will soon discover an alien species. Why not BE that species. I mean, you'd have to run from their law enforcement to prevent being dissected, but hey........that's the risk of a fun adventure. While humanity is fine, not every species is. Your presence may trigger something big. Who knows?
Dodging some asteroids, fighting space pirates, spacial exploration outside the ship, mechs, hyperspace, lightspeed, running from wormholes, the works
Floating cities, Livable Airships, underground civilizations, non-earth planets colonized being considered Earthen continents and an international law prevents any one country from trying to claim it as their own. This along with every other planet in the solar system is claimed as humanity territory, this part of the Milky Way considered the Human Galaxial Territory. Space sailing is as common as commercial flying across the earth or sailing the earthen seas.
