Some supposed giant bones are art
Others are bogus.
They make us wonder, "what if?"
We are fascinated with giants from humans with gigantism conditions of the pituitary gland to Goliath, the beanstalk giant, and Gulliver.
What if we were at the mercy of something 10 times our size? Giantasophobia - fear of tall people.
And, what if giants are among us an we have yet to recognize them?
