In the 1800s, atheist George Hull had an argument with a Christian over whether giants once roamed the earth. Deciding that people will believe anything in the Bible, Hull carved a statue of a giant man, made it appear petrified, and buried it in Cardiff, NY. He waited over a year before unearthing the ‘Cardiff Giant’, charged people to come see it, and by the time it was revealed as a hoax, he’d made today’s equivalent of $430,000. Source
