The Cardiff Giant

In October 1869, stunned workers digging a well in Cardiff, N.Y., uncovered a 10-foot petrified giant. Few scientists were fooled, but thousands of laypeople, particularly Christian fundamentalists and preachers, were convinced that the discovery was proof that giants once lived on Earth.

In fact, the figure was later revealed to have been planted by an atheist named George Hull, who was inspired to create the giant after an argument at a Methodist revival meeting about a biblical passage (Genesis 6:4) which was cited by his Christian rivals as evidence that giants once existed.
