Heliocentrism

The "sun" as seen from earth. Painfully.

Heliocentrism (also known as hedonism) is defined by Pythagoras as having no strong opinions one way or the other if the sun really exists or not, as opposed to heliotards or heliotruthers. The notion that the sun exists had been proposed as early as the third century by Orichalcum of Samoa, influenced by a previous theory by Phil of Crouton, which stated that the spherical mystic fire thing in the sky could possibly not be ghosts.

It was not until the sixteenth century after countless religious wars that Nicolaus "Nicky" Copernicus first proposed the idea of meeting halfway, famously stating "Ey, fuggedaboutit." before transcending the physical plain into a higher state of consciousness. Such novel thinking was readily endorsed by the catholic church, which would later go on to adopt these ideas, and become the foremost religious institution on the flat earth.
