It has recently come back into debate..
half a million years ago early cave dwellers(homo erectus - homo habils) carved,drew or painted supernatural objects and shapes among the walls, now it is also said that early homo erectus would not of had the capabiltiy to lie (i dont know how exactly its not my field) so if our early bipedal brothers wasn't capable of lieing then did they base their drawing on a true story??? i would love to have opions!
