Why do people laugh at creationists?

A worthwhile set of videos. Some of the responses are just snarky. I understand that creationists are just silly. One of the last about the water above sky and how it's nearly impossible to prop it up there is kind of odd. Frankly it seems that in geosync orbit you could have a bunch of water pretty easily floating there without needing to drop to earth. Though still, way too much water. Though that would be totally awesome to have. A bubble around a planet in geosync. The water above the sky refers to the Biblical firmament. Hovind (who made the claim) is right, according to the Bible the world is flat and there is water in the sky which leaks out when it rains (probably also explains the color of the sky). It is a rather silly claim, but only like 50% of Americans believe this crap so it's pretty much moot.
