DNA testing wouldn't tell you whether that was the front or rear view of a skull
I looked at the Starchild site, and it does indeed appear to be the front of a skull, although one that is missing the Nasal, Nasal Sceptum, Zygomatic, and Maxillia bones.
The Orbits, Frontal and sphenoid look to be pretty deformed though. The Frontal bone looking very much like the Occipital bone in a skull (being the bone immediately opposite the frontal on the back of the skull). As for it being 1/2 as thick/massive and 2x as strong
Since I have not seen the skull, and do not know how they came to this determination
The Layer of "Shellack" applied by teh discoverer of the skull probably has something to do woth that fact
as do the several less than professional proceedures that seem to have been applied to the skull.
There are several facts that are presented in the "StarChild" site that are blatantly ignored: Its location when it was found, and the effects of skull deformation, which are highly present in the populations of the area it was found at the guessed at age.
The location where it was found indicate that it came from a culture that practiced Skull-Deformation. Pretty much ALL South, and Meso-American cultures in the Pre-Columbian Period practiced Skull-Deformation of one kind or another. Many continue to do so to this day.
They also point to the cranial Sutures as "unusual", being too closed to be a child, yet not fully developed like an adult. They seem to TOTALLY Ignore the fact that skull-deformation tends to mutate the cranial sutures in pretty unpredictable ways. They will both close and fuse prematurely, and will tend to form structures that are not usually present in ANY skull that has not been deformed in some way.
They also make a big deal out of the piece of maxillia that has been found; indicating that the presence of unerupted (not grown in) tooth buds indicates that it was a child, yet the level of erosion on the erupted teeth is too great to be that of a child. This completely ignores the fact that the foods of a pre-industrial culture tended to be rougher and contain contaminents that erode teeth much faster than do modern foods in the same environments. Peices of stone present in breads and grain foods from the methods of grinding the flours made with grains during the period were completely ignored by the site
Also, the "fibers' Inside the skull could be the result of some abnormality such as Cruzoun's syndrome
Which they later make a comparison of, along with another "Abnormal" skull, both of which share MANY of the "StarChild" skull's properties (Flattened skull, closed/fused sutures, shallow eye-sockets/orbitals, etc
)
The process of cranial deformation is something that is present in a lot of civilizations in the Americas and S Pacific island cultures. Considering that there has been some recent discovery of genetic links between Several Lower American Native populations and those of Pacific Islanders
It is not surprising that these practices are shared by these cultures.
As to "why".. It is a practice that is designed to emulate the "Gods" of these cultures.
Most of the images of "Gods" (and even of Aliens) are what is known as latent Archetypal imagery
They are deformations that are present in a sort of body form that we have in our sub-conscious. Also, sort of ftrangely, they are also exaggerations of the proportions of a child. There has been a great deal of discussion as to why these images tend to replicate those of an infant human or primate (as infant primate skulls are VERY similar, even between species)..
I doubt that there were aliens present who caused their own veneration among ancient man
There is just no evidence for such a thing, and it is a wild eyed idea from dreamers who have more imagination than they do sense
I find it very interesting that the cultures where aliens are supposed to have visited did not progress beyond certain points
They may have made "great leaps" in technological or scientific progress at one point, but these "leaps" failed to carry that civilization very far
The Egyptians barely grasped the significance of the wheel, the American civilizations didn't grasp that significance at all. Their math never progressed beyond basic algebra, and what has seemed, until very recently, as astounding mathematical and astronomical feats, have proven to be just simple constructs that used multiple error checking routines to produce fairly accurate astronomical alignment
Then, these cultures just sort of stalled, and went nowhere else until another more advanced cultue came along to supplant them (Europeans in the case of the Americas, Hittites and then Greeks in the case of the Egyptians
Come to think of it
The Greeks came along to a lot of these civilizations, and they never really have been promoted as having been visited by aliens
Of course, there is always someone out there who will claim that all cultures were visited by aliens at one point or another)
Last point about the SC skull
I could not find in their site anywhere where it said WHO was doing the testing on this skull
The one name that I found is in CA, NOT in Vancouver BC, where they claim the testing was done (Trace Genetics, which after I looked them up have not been in business long enough to have done the testing either)
I can find no other references to any institution, only to a few individuals who are listed in several papers
I bet if I look them up, they will all prove to be either crackpots or will have had their fidnings taken out of context.
