And here we go with the bullshit again. These are all easily explained. You can find them all in about three seconds with Google or look on Skeptoid. Some of them are real, like the Antikythera Mechanism and some of them are complete bullshit, like the 'Baghdad Battery'. I'm so sick of this pseudo-history, mystery-mongering bullshit. Grow up and educate yourself instead of buying into nonsense. Real history is a thousand times more interesting than phoney baloney idiocy.
