does he believe that the earth is flat and support by 2 elephants on a turtles back?

haha, yo i asked him that to him the first time he started jivin' about this nonsense, and he's like "no, that makes no sense"...i just laughed

I would go with the fact of gravity... and the fact of all the orbits... obviously the sun is the center... just use a telescope and he can see for himself.

and this way the "secret governmental agencies" that are covering up the fact about the suns orbit have no sway on what you are seeing through the telescope... IDIOT! People that are that ignorant ...

he says the man's covering it up is a part of a conspiracy that's goal is to take our reasoning as far from the bible as possible, because, the bible supports geocentrism...rrreeeeetard

Have you asked him to show you from the bible how it supports geocentricism?

yeah but he'd never actually bring it in..and never quote anything either...he just likes bickering basically...simple minded fella

If that's the case is it even worth your time and effort to try and talk to him about it. It may just be a case of pearls before swine.
