here we are, as humans, only stuck on Earth, yet somehow able to decipher and conclude all we know about the universe, all the galaxies and all the many planets out there even out of our solar system.
How the hell can we humans know, just by looking at some telescope from planet Earth at things that are so far, millions of millions of light years away?

What if we were wrong all along? What if out there, it's just one big black screen of planet drawings that we're looking at. Or just some 3D simulation? Or maybe one big ass wall of painting

How do you know your monitor isn't just showing a bunch of random scribbles painted on by invisible mice.

How do you know you're writing what you think you're writing?

What if scientists did the maths all wrong? What if the planets don't look small because they're far away but look small because they're just that small?!

ok good, I don't believe in the universe anymore. There's no universe. The Earth only exists. Everything you see in outerspace is one big fake background
