This will blow ur brains How do we know that we don't live in a box and the stars are just poked in holes so we can breathe and that the holes were poked in paterns so that the early astronomers didn't get bored. ALSO what if the star is just a big flashlight and the moon is a big glow stick in a ball And what is the pictures of space are just drawings i mean we have good drawers in this box. AND how do we know that the video of the first man on the moon wasn't on a green screen
