This is simple and the evidence abounds. More importantly it is logical and conforms with all known experiment. Not to be overlooked is that this "theory" is "reality" itself in terms of ancient science. I understand the irony here as well as the apparent circular reasoning but the observation and logic create "theory" (thot) in terms of Ancient Language. It is homage to "amun" Himself.
Be that as it may every point still stands. There is evidence for an Ancient Language. There is evidence for a world wide language 10,000 years ago and there is evidence for changes in the human "species". This theory has made many predictions and most have never been tested but all that have been tested have been shown to be true.
The language will never be really translated. It can not be translated. Any reasonable attempt at translation will look like a flow chart. I would do this myself but it would be crammed full of jargon and esoteric, hard to follow, logic. Most is situational so unless you're actually there and see what's going on it will be nearly opaque. In other words actual translations are meaningless to English speakers and only discernable to experts who won't be able to see the logic unless they believe it exists. There is no gain since people won't even believe interpretations based on the ACTUAL LITERAL MEANING of the words.
How odd that archaeological beliefs that ancient people relied on superstition and magic is never questioned!!! How odd that people today believe agriculture and cities were invented with no theory at all!!! How odd that people believe it is only natural that there are no written records dating back to the invention of writing!!! How odd that our species wide amnesia is considered normal!!!
I'm am simply telling you based on the physical evidence why such anomalies exist. Every species has its own natural species specific science. Ours was merely more complex because our language was more complex so each generation stood on the shoulders of the one before.
You can't "read" their writing. Your brain has been rewired to parse words and their words could not be parsed. I can show you the intended meaning since the intended meaning is hidden right inside the literal meaning. It's the same way with communicating with animals. We don't format speech or communication the way they do. Cave men understood no abstractions and almost every word in modern language has some level of abstraction in its meaning. Their language was mathematical, binary, representative, and metaphysical. Our language has none of these characteristics and it is formatted differently. They can never be translated. They must be interpreted in terms of the literal meaning.
All of that, are just bunch of claims, cladking. None of them are evidence.
The claims, are “made up”, as in your “invention”, which you have no evidence. You are claiming knowledge of 40,000 people that possessed language and science that don’t exist, except in your speculation, and in your fantasies and delusions.
You are metaphysician and a generalist, essentially a philosopher, with no education in biology (including neuroscience, since you have brought up brain), in paleontology, in philology, in archaeology, and so on.
You really never study any language other than English, so how can you even they think logically or think metaphysically. You invented narrative to the 40,000 years ago people, which are purely speculative.
Plus, science is about knowledge that can be explained, as there are no language to study 40,000 years ago, no such explanations exist. Science isn’t about logic alone: knowledge/explanations required to be testable, and only tests are observations, and these observations include evidence (including experiments) and data. It is with these evidence that you would verify if such explanations are true.
You have claimed you have “all the evidence” or all the experiments, but not once, have you supported your speculations, your narratives and your claims, with these massive numbers of evidence at your disposal. Which means your so-called evidence, is another bogus claim, where the evidence don’t exist.
You have never studied any human fossil, nor have you ever study human brains before, living or dead brain - and when I mean study, I mean real experiences in examining the evidence, such as the brains or fossils.
Remember you have some argument with someone in the past, about brain biology, person or people have to corrected you, repeatedly.
You have never touched or studied living brain before, have you?
You have never touched or studied fossils before, have you?
And you have never deciphered or translated any non-writing ancient symbols before, have you?
You never have any evidence, cladking, just a bunch of circular claims that you can justify with your (confirmation) biases.
Until show actual evidence, your fantasies are just that, invented narratives, that have no basis of reality.
