Do we see reality as it is? (IM 569)

Before 16th Century, people all around the world believed that earth remains still and all other component revolves around the earth. But Copernicus and Galileo told that it was the earth that revolves around the sun not the opposite. In the same way, people used to believe earth is flat until Pythagoras told it is an oval shape. There might still be lots of such fallacy that we are trapped in. The reality we see today might be wrong. There is a chance that whatever we believe isn't true at all. It's just a perception of somebody else and we have been following it for centuries and will be following for centuries to come. So the way out is not to fall in the trap of reality. Nothing is real in reality; it might just seem real until somebody proves that it's just the facade misconception.
