Someone who ignores the scientific evidence of an old Earth, common descent, evolution, history, archaeology, well-known facts about chemistry and physics, etc. to insist that the entire world was created a few thousand years ago merely because it says so in an ancient book written by shepherds.
Typically found visiting websites like "Answers in Genesis", demanding that "warning stickers" be placed in school biology textbooks, and homeschooling their kids to save them from evil men like Richard Dawkins.
1. "Hey, did you see those creatards lining up to buy tickets for Ben Stein's 'Expelled'"?
2. "Mom, Holly's dad told me that the whole world was made in 4,004 BC in less than a week's time. Also, that Noah put all the world's animals on an ark for forty days to save them from the great flood. Later, Moses led 600,000 Israelites across the desert for 40 years and God gave them food by magic!". "What a creatard!!".
A creationist that ignores any evidence of the contrary. They're reasoning is usually that of a retard and it's evident when you speak to them.
Those creatards are saying evolution is false? What dumbasses.
