There is some very exciting new work being done in paleo-anthropology in reinterpreting previous archaeological finds. Because of the middle east prejudice, it was always assumed that Europeans thousands of years ago were illiterate and rather dull-witted. It was assumed, for example, that they learned metallurgy from Sumerian traders (that the Sumerians traded into the Balkans is something for which there is a written record). It was also assumed that the symbols they made were just imitative of Sumerian cuneiform, and were not actual written languages. But Bulgarian archaeologists have been insisting for decades that evidence for copper mining and smelting, and tin mining and smelting and bronze smelting found on the eastern slopes of the Balkans dates to a time well before metallurgy in the middle east. Since the collapse of the Soviet Union, western investigators have been able to go in and look at the evidence, and most of them are convinced. (Older academics with a published "turf" to protect make up the bulk of the remaining skeptics.)
This is not to say that the Sumerians got metallurgy from their trading partners in the Balkans--nobody could answer that. But it does throw out the previous assumption that Europeans got their metallurgy from the Sumerians. On the basis of that upheaval to previously held notions, younger investigators have been looking at a whole range of previous assumptions. One that really inerests me is the question of whether or not Europeans of the Upper Paleolithic and the Copper and Bronze ages actually were illiterate. There are systems of symbols, dozens of symbols, which are ubiquitous in Europe, which many researchers now think may well have been a coherent system of writing--in fact, there are at least two major systems, one using markings, and the other accumulations and groupings os small clay, bone or wooden markers, like the chips used in casinos. The current sense of their use was as markers in an inventory/accounting system.
On the islands of Malta and Gozo there are huge megalithic structures, and recent topographical studies show that the two were one island 20,000 years ago, and may have been connected to Africa and the Italian mainland. Remains of pygmy elephants and other African species have been found there, as well as remains of European animals that had not previously been thought to be native to Malta. Their culture was flourishing long before others in the middle east arose. This megalithic temple:
. . . on the island of Gozo is the oldest, surviving, free-standing megalithic structure in the world. It dates to more than 5500 ybp. The culture which built the temples seems to have disappeared for no reason which is obvious, as did those which preceded it. Mankind arrived at least as early as 20,000 ybp, and are considered to have been of Iberian origin (genetic studies? i'm not clear on why people think that). Some modern researchers say that markings found there may be related to the symbol systems used in Upper Paleolithic Europe--and the bolder ones say it was coherent writing. Some go so far as to relate the un-deciphered Linear A of Crete to the UP symbols from Europe, and speculate that they may have reached Crete from Malta/Gozo. I can't speak to the reliability of the claim. Linear B has been deciphered and is the oldest form of written Greek (about 3500 ybp). But attempts to decipher Linear A based on Linear B produce gibberish. It seems clear that Linear A is written in a different language. Linear B predates any written Greek on the mainland by several centuries.
The most extravagant claim is that Linear A and the earliest writing in Egypt (which is not necessarily hieroglyphic--heated controversy rages bout that, though) are direct descendants of the UP European symbols systems. The most convincing reason to reject the cultural diffusion hypothesis (once alleged to have been a scientific theory) is precisely that our ancestors for more than 100,000 years were uniformly as intelligent as we are, so it is silly to suggest that they couldn't come up with metallurgy or writing on their own, and had to wait for the cousins of Abraham to come along and enlighten the poor, benighted souls. We can read Linear B because it's in an early form of Greek. We can read Sumerian because of a sound "chain of custody" from their writing to later forms of writing known to the Greeks. We only were able to read hieroglyphs and hieratic script of Egypt because of the Rosetta Stone. The earliest markings found in Egypt were at Siwa, and some claim they are not related to hieroglyphs or hieratic (another hotly debated claim). There are those who suggest they are related to the UP European symbol system (this usually leads to fist fights).
But there is no Rosetta Stone for the UP European symbols, so we likely will never know with any certainty whether our ancestors there were truly literate.
