To say that they are anything one way or another. Maybe they were simply bullets for a giant gun from the world favorite supervillain of the time .would be difficult without actually being there when they were made.
In pouring rain when everything is soft, slippery and muddy is when they would have been rolled along into the places where those people would have wanted them. Humanity, Health, safety and sanity is important. Anybody would have done the same obviously even the Egyptians show how they did it on paintings on the walls really 😀💀🏝🌞🌦♥️⛄🌟💧🌎👍🐴♦️
If you look at the heads from a artist point of view the nose is flat so that it doesn't break when being rolled .also the forehead being larger to protect the facial features when being rolled. Now look at it and think of a different nose. Looks to me like a Roman helmet . On a Roman. Or not Sometimes the simplest concept is correct
I never take carvings as what people actually looked like..carving stone isnt like drawing someone. Not to say they arent of African decent because they could be but carvings dont tell you this is what they looked like.
