The Brief: Astronaut with a gun "always has been" memes are used to make over-dramatic reveals.

DEEP DIVE
Astronaut with a gun memes or “wait it’s all/always has been memes” come from the Ohio takes over the world meme of February 2020. According to Know Your Meme, Ohio memes that include an astronaut with a gun first appeared in late 2019 and rose to popularity in early 2020.
One iteration of the Ohio memes depicts two astronauts in space overlooking Earth, which consists of a single landmass in the shape of Ohio. One astronaut says “wait it’s all Ohio?” and the other astronaut, who has an Ohio flag on their suit, says holds a gun up and says “always has been.”
Always has been. from memes
The idea of a massive conspiracy that the whole world is actually just Ohio has inspired other variations using the same format where someone reveals an earth-shattering fact. Usually, these reveals are comedic and absurd, such as that earth is made of chicken tenders or that ratatouille is all vegetables. “Wait it’s all/always has been” astronaut with a gun memes are particularly popular on Reddit.
