haha, thanks for the pics...the thing is, his argument is that "the man", or, the folks in charge of what we learn in school, rigged everything so that we end up believing a lie...so illustrations wouldn't mean much to him - what i want is some sorta like undisputible line of reasoning, or equation, that'll shut'm up
since he doesn't believe pictures and they are "lies" star with the pictures of himself and actual things that are "now" and ask him if they're lies also....then proceed to show him pictures of the solar system etc.
OR
act like the total "airhead" and ask "if the sun revolved around the earth, it would have to be at lightening speed, now since its going fast wouldn't the fire/gases etc burn out and not give us heat?" then just walk away....hahahaha
