Also “flat” and “round” can be proven to a certain degree. “Planet” is subjective.

“Planet” is a definition which by definition is what it is defined to be, or otherwise it will not define anything and by definition be useless as a definition. Arguing about definitions will not change the facts, only the way the facts are presented. So get back to arguing about whether colonizing ur bum, amirite? is funny.
