Holy shit.

I’ve never been alive in a time when every human has been on Earth. That’s crazy to think about…

If you like pedantry, people have definitely flown in vehicles and even jumped.

I like pedantry but want to go the other way. The ISS orbits in the thermosphere, still inside Earth's atmosphere. I say that you haven't really left Earth until you exit the atmosphere.

i mean, even those guys who went to the moon still stayed within a very close proximity to the earth compared to the size of the solar system

only when people travel to mars they will really have left the earth
