I believe the first written texts and alphabet were found at Ur of the Chaldeas. So it is possible that Moses wrote the Pentateuch.
FROM KARL RANDOLPH: Lets go back to archeology: unless the reports I heard were wrong, the tablets at Ebla mentioned that there were two cities named Ur, one was Ur of the Sumerians and the other Ur of the Chaldeas. Two, the Bible (the only ancient document that records Abrahams existance) states that he came from Ur of the Chaldeas. The conclusion I draw is that the Bibles claim rules out that Abraham was from Sumeria.
So there were a lot of Semites who intermingled with the Sumerians? That doesnt change the above equation, unless you can show that Ur of the Sumerians and Ur of the Chaldeas were one and the same city. Then how do you explain the Ebla reference? Karl W.

First Alphabet Found in Egypt Volume 53 Number 1, January/February 2000 by Elizabeth J. Himelfarb
Along an ancient road in Egypt's western desert at the Wadi el Hol (Gulch of Terror), Yale archaeologists John and Deborah Darnell have discovered two inscriptions representing the earliest-known phonetic alphabet. The script, which incorporates elements of earlier hieroglyphs and later Semitic characters, was carved into a natural limestone wall alongside hundreds of Egyptian inscriptions about 4,000 years ago.
Although a few glyphs look familiar to readers of semitic languages and ancient Egyptian, the alphabet has not yet been deciphered. "Within a couple seconds you realize it's pretty odd-looking," says John Darnell. http://www.archaeology.org/0001/newsbriefs/egypt.html
THE FOUR VEDAS... together represent ancient Hindu thought at its most beautiful and esoteric and belong to the period 1500 - 1000 BC. wwww.indiaheritage.com/religion/hindu/vedas.htm
VEDAS not old enough.
So, no, the Bible does not predate the Vedas, no matter how much you'd like them to.
