Errors in the Quran
The most serious problem for the Quran is that it repeatedly claims the Bible was not correctly preserved by the Jews, and that it has the real account of what transpired... but the discovery of the Dead Sea Scrolls shows that the Bible has been accurately preserved for over 2,000 years - directly contradicting the Quran.

Dead Sea Scrolls

 * See also List of Dead Sea Scrolls

In 1947, in the midst of the War for the Independence of the Republic of Israel, came the discovery, at Qumran, of the first 7 Dead Sea scrolls by a Bedouin shepherd boy looking for his straying goat. Bedouin of the Ta'amra tribe discovered 7 scrolls in a cave now named "Cave 1" Khirbet Qumran on the Northwest shore of the Dead Sea. Three of these scrolls were then purchased by archaeologist Eliezer Lipa Sukenik for the Hebrew University and others were bought by Mar Athanasius Samuel for the Metropolitan of the Syrian Orthodox Church in Jerusalem. From 1949-1954, additional fragments of more than 950 different scrolls were found in 10 nearby caves by Bedouins and a joint archaeological expedition led by Professor Father Roland de Vaux for the École Biblique et Archéologique Française and the Rockefeller Museum.

The discovery of the Dead Sea Scrolls, most of which dated from 200 B.C. to 68 A.D., drastically increased our assurance that the Old Testament we have today has been faithfully transmitted through the centuries. Some even date to 300 B.C. or older, like the Great Isaiah Scroll which was carbon-dated as old as 335 B.C. These scrolls have largely backed up the Masoretic Text, with rare exception. The most manuscript fragments were found in Cave 4, over 15,000. The final cave, Cave 11, was discovered in 1956. The first 7 scrolls remain in the property of the Israel Museum, while most of the fragments are owned by the Israel Antiquities Authority (IAA).

There were actually five sites in all discovered contributing Dead Sea Scrolls. The first, at Qumran, consisted of 11 caves with over 15,000 fragments (according to the Dead Sea Scrolls Foundation there are over 100,000 fragments from 800 or 900 original manuscripts, typically dating from the 3rd to 1st centuries B.C. The second site, Wadi Al-Murabba'at - 11 miles south of Qumran, contained documents from army fugitives in the Second Jewish Revolt against Rome (A.D. 132-135) and included a well-preserved scroll of the Minor Prophets. The third site south of 'En Gedi included a Greek translation of the Minor Prophets from the 1st Century A.D. and some Biblical fragments. The fourth site, 8.5 miles north of Jericho, contained legal documents from Samarians massacred by soldiers of Alexander the Great in 331 B.C. The fifth site at Masada contained a copy of Ecclesiastes (75 B.C.) and fragments of Genesis, Leviticus, and Psalms.

Mary, Mother of Jesus and Sister of Aaron?
One major error in the Quran involves the combining of Mary the Mother of Jesus with Miriam, Aaron's sister. Although thousands of years apart chronology, the Quran confuses them as one person.
