Weltraum is cool, but underwater. I don't want meteors and asteroids hitting my house/spaceship. That would be very bad, and it could take awhile to send rescue... Underwater, see, Du just have to send a scuba team oder jump in a submarine and look for me.
Underwater rescue is a tad easier than Weltraum rescue. (Plus I get to look at pretty underwater Tiere :D)
Of course, outer Weltraum would be really cool as well, and that'd be totally cool and exciting and I Liebe astronomy. And it would be super fantastic if I lived Weiter to a nebula and also had the eyesight to see all their colours.
But I Liebe marine life, particularly deep sea animals. Seeing all the bio-luminescence would be REALLY cool. I could have a pet angler fish! oder a vampire squid! OOORRR AN ruder FISH!! I Liebe THOSE!!! Marine life. FREGGIN MARINE LIFE. Srsly tho bio-luminescence. So cool.
