The "Always Has Been" meme is a humorous take on conspiracy theories and the realization that things might not be what they seem.

It typically features two astronauts. One astronaut is on what appears to be the moon, pointing a gun at the other. The astronaut being held at gunpoint turns around to reveal that they (or the moon itself) are made of cake (or some other unexpected material). The first astronaut then asks, "Wait, it's all [unexpected material]?" The second astronaut replies, "Always has been."

The meme is used to satirize situations where a shocking truth is revealed, often questioning established narratives or exposing hidden realities. It's a playful way to express skepticism and challenge assumptions.
