It's the Nephilim! Actually a very clever cut and paste job. Compare the shadow of the guys in the white shirts to other items. The guys in the white were there at noonish while the rest of the image shows long afternoon,l early evening shadowing.Iggy,
You can't do this to me! You can't just post pictures of a giant skeleton without some details. Who, when, where, how? Dude, I won't be able to sleep tonight!!!!!!
The others posted after the first grouping I couldn't tell you if real or a hoax. Do some googling and you'll find there is a plethora of giants world wide found at various times in history.
Sure looks cool.
