Random Conversation #2 - Monkeys

While talking to this chap at a recent gathering, the conversation touched upon a rather touchy topic. I tried to be the voice of reason, for once.

"Those could just be underwater islands, you know. Or shallow coral reefs. Or maybe the sea-level rose to submerge some parts that were above water once, giving the illusion of a submerged bridge."
"Pah! Those are just theories. Why would I believe them any more than what's in the scriptures?"
"Well, quite simply because there is irrefutable proof. There are studies performed by the geological society, photographs from NASA. All point to the fact that it is not a man-made structure."
"Of course it's not man-made. It was made by monkeys."
