Ancient Greek philosophy questioned the natural causes for life and if they truly exist. One example was about a very famous cave theory. There were 3 men who were chained so they had to only stare at a wall with shadows of the people and things going on behind them. Every single day, they thought that the world was only dark and 2D. Until one day, one of the people escaped and had the chance to go out into the world that the person did not know existed. Once he saw the sun, it blinded him but after a second, his eyes adjusted and realized that the word was completely different compared to what he thought it was for decades. The first thing that the prisoner did was go back inside of the cave and tell the other people the incredible things that he had seen. The cave was more dark due to the bright sun, and he was slightly blinded. Once he told everyone what had happened, they did not believe him and thought that it was a bad thing due to the fact that the freed person was blinded. And so, they killed the prisoner and continued their lives never knowing about 3D images, and that all of their surroundings were incorrect.
