A long time ago people who didn't know any better swore the world was flat..........didn't really matter what they "believed" though did it?
And there was some self-proclaimed "scientist" that swore that the round-world scientist was on the payroll of the king.
*Note: That same nay-sayer was later credited with discovering halucinogenic mushrooms, inventingthe all-male bath houseand is believed to be the world's first suicide victim.
He knew some **** in his day, though, huh?
