It's where the terms; 'living under a rock' and or 'living in a cave' come from. As in say I don't know something mainstream a person may say "what?! you don't know that? have you been living under a rock/in a cave? all your life..."
Weeeeeeeeeeeeelll from what I know of this and what I know is FACT, because it is I how is knowing what I know that is how the know is what I fact.
The Allegory of the Cave was story thingy from Greece about people chained up in a cave not knowing anything of the outside world, seeing only the shadows on the walls and shit, ego my statement could connect to such.
