Today I stumbled upon an amazing structure. It was Dolmen in Saint Michel de Grandmont in France.
This Dolmen is an exceptionally wonderful and heavy structure we have ever found on earth. We practically don't know how neolithic people made this structure. If you see it closely, you will find that it is well ventilated as well. Could it be possible that the giants made it? If yes then why don't we have practical evidence of them? could people of that era build used some left out tech by aliens?
