The true history of Europe is destroyed or subverted due to two great evils which are the same (YHWH):
First christianity defiled everything and labeled everything authentic, Good, and european as evil.
Second, in our modern times liberalism does the same.
You can also clearly see that both YHWH's cult and liberalism (under the guise of science and anthropology) has a vested interest into convincing us that the Middle East is "important" and other stronger claims.
My simple theory regarding neolithic european scripts is that they are connected to chinese oracle bone script. Meaning, there was communication via eurasian steppe, or more likely a protoculture fully unknown and primal from which both the White race and Asians derived the initial spark. Miguel Serrano claims that a certain old guy who was in the Ahnenerbe (I forgot his name) researched this, and he spoke to him just prior to fully blown WW2. He also wrote a book. Basically there was a city state or small civilization in the Gobi desert prior to the end of the Ice Age that got destroyed and which achieved writting, metallurgy etc. Nothing sci-fi, but pretty damn impressive.
The writings in caves across Europe are remnants of remnants of that, of those people who survived the destruction. It is possible their progeny had very little understanding of their heritage.
The book mentioned above cannot be found anymore, because like thousands of books it was destroyed by the Allies and blacklisted at the end of WW2. Basically we will never know the truth. It was found, and then burned. You can see the same occuring in Alexandria previously (YHWH's christian slaves) and so forth.
