If we were born in a vacuum, it'd be like being born in the ultimate cosmic chill zone—no air, no gravity, just us floating around like astronaut superheroes. But hold up, 'cause, without air, we'd be gasping for breath faster than you can say "space cadet." And gravity? Forget about it! We'd be bouncing around like those bouncy balls you used to play with as a kid. Plus, without the Earth's atmosphere to protect us, we'd be roasted by the Sun's radiation faster than a marshmallow on a bonfire. So yeah, being born in a vacuum might sound cool in theory, but trust me, it's a total vacuum of fun!
