The errors in Quran disqualify the Quran as the word of God, who is perfect and does not make errors. Many of the errors in Quran are self-contradictions that naskh tries to cover up. But the Quran also has archaeological errors, historical errors, errors in logic and even elementary mathematics.
For example, the Quran claims that one night, God took Muhammad to the "al-Aqsa" mosque is in Jerusalem:
"Exalted is He who took His Servant by night from al-Masjid al-Haram to al-Masjid al-Aqsa, whose surroundings We have blessed, to show him of Our signs. Indeed, He is the Hearing, the Seeing." - Quran 17:1
The Muslim army conquered Jerusalem in 637 AD and the al-Aqsa mosque was completed in 705 AD. The problem with the above passage in the Quran is that Muhammad died in 632 AD, which was 5 years before the Muslim army reached Jerusalem and 73 years before the al-Aqsa mosque was built.
Or consider Quran 20:92-95, which claims that Moses confronted "Aaron" and a "Samaritan" for having made the golden calf for the Israelites while he (Moses) was on Mount Sinai:
"[Moses] said, "O Aaron, what prevented you, when you saw them going astray, from following me? Then have you disobeyed my order?" [Aaron] said, "O son of my mother, do not seize [me] by my beard or by my head. Indeed, I feared that you would say, 'You caused division among the Children of Israel, and you did not observe [or await] my word.'" [Moses] said, "And what is your case, O Samaritan?" - Quran 20:92-95
Assyria conquered the Jewish northern kingdom in 722 BC, exiled its upper class and brought in conquered people from other lands, who intermarried with the lower class Jews who had been allowed to stay. Their offspring were called "Samaritans" because they occupied the region of "Samaria," which was named after its original owner, "Shemer" (see 1 Kings 16:24 in the Bible). The Jews despised the Samaritans both for being a mixed race and for setting up their own temple to compete against the temple in Jerusalem.
But the golden calf incident near Mount Sinai mentioned in Quran 20:92-95 above took place in 1446 BC, which was 725 years before the first Samaritan was born in 721 BC.
It gets worse. For example, How Old Was Mary When She Had Jesus?
