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 “petrified” statue of
a giant man 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 his hoax
was revealed, he’d made about $430k. Source Source 2 Source 3
