Have you ever checked the Papuans in New Guinea?? Why would they wear a bone in their nose, or a big shaft to support their private parts? Because they want to look like their gods who came down from heaven?
People just love to add things to their bodies and and change parts of their anatomy to be seen as special.
It's quite common that the heads of babies are misshaped after passing the narrow birth channel. People through the ages have noticed that, no doubt. But after a short time, the heads return to a normal shape. Well, it appears that many people from the past loved the way the heads of their newborns were shaped, and wanted their heads to stay that way, and so they binded the heads of their newborns to force their heads to change into the preferred shape.
You should have a talk with midwifes, and ask them how the skulls of some of the babies of their clients are shaped right after they are born.
Again, you seem to be missing the point. Unless it's changed in the last few months, last time i checked, it ain't fun to bash your skull in fact quite the opposite, why would you bash your skull and put yourself through so much pain? For what, fun? So as to make it longer and mishapen. My point from this being, i doubt they would put themselves through such a painful and unpleasant experience for fun or decorations. There must have been a serious need or a serious being whom originally had a skull this shape. And they wished to be like this being and hence they bashed their skulls into this shape. Maybe what the ancients considered "Gods", what the Egyptians called Sun Gods, were.... dare i say it..... REAL?
These are the facts.
This BEING had a skull with twice the natural capacity of a human being and judging from where the atlas from the spine would have gone in, it would have been at least 12 ft tall. That's no human.
