The doctrine of Twelver Shia is false according to the Qur'an

I am confused, first this debate is about the doctrine of twelver Shia, but then I changed it to is the Qur'an violent because of Con's argument now he is going for supposed errors in the Qur'an?"The Qu'ran is thought as to be a holy book. If it is a holy book why does it have so many historical errors? In Sura 2:241 Muhammad confuses the persons of Saul and Gideon."2:241 "And for divorced women is a provision according to what is acceptable - a duty upon the righteous."How is this verse related to Saul or Gideon?(http://quran.com...)"In Sura 2:55-60 the Israelites were said to be "a scanty band" vastly inferior to the Egyptians. But in Exodus 1:7-10 the Egyptian king said to his people that the Israelites had become "more and mightier than we"."Let us read 2:55-60 "And [recall] when you said, "O Moses, we will never believe you until we see Allah outright"; so the thunderbolt took you while you were looking on.Then We revived you after your death that perhaps you would be grateful.And We shaded you with clouds and sent down to you manna and quails, [saying], "Eat from the good things with which We have provided you." And they wronged Us not - but they were [only] wronging themselves.And [recall] when We said, "Enter this city and eat from it wherever you will in [ease and] abundance, and enter the gate bowing humbly and say, 'Relieve us of our burdens.' We will [then] forgive your sins for you, and We will increase the doers of good [in goodness and reward]."But those who wronged changed [those words] to a statement other than that which had been said to them, so We sent down upon those who wronged a punishment from the sky because they were defiantly disobeying.And [recall] when Moses prayed for water for his people, so We said, "Strike with your staff the stone." And there gushed forth from it twelve springs, and every people knew its watering place. "Eat and drink from the provision of Allah , and do not commit abuse on the earth, spreading corruption."Now please how is related to what you have said?"The Koran confused the sister of Moses (Miriam) with Mary, the mother of Jesus. In Hebrew, Miriam and Mary are the same names."Does the Bible confuse Jesus son of Mary as Jesus the son of david? no, It is the same thing with the Qur'an, they named Jesus as son of david because he is righteous, samething with Mary as the son of Aaron.Mughira b. Shu'ba reported: "When I came to Najran, they (the Christians of Najran) asked me: You read "O sister of Harun (Aaron)" (i. e. Mary) in the Qur'an, whereas Moses was born much before Jesus. When I came back to Allah's Messenger (may peace be upon him) I asked him about that, whereupon he said: The (people of the old age) used to give names (to their persons) after the names of Apostles and pious persons who had gone before them. (Translation of Sahih Muslim, The Book on General Behaviour (Kitab Al-Adab), Book 025, Number 5326)"This Hadith clarifies it."How many angels were talking to Mary? When the Qur'an speaks about the annunciation of the birth of Jesus to the virgin Mary, Sura 3:42,45 speaks about (several) angels while it is only one in Sura 19:17-21. The Christian Bible clearly indicated one angel; "In the sixth month, the angel Gabriel was sent by God to a town in Galilee called Nazareth," Luke 1:26"In Sura 3:42 "And [mention] when the angels said, "O Mary, indeed Allah has chosen you and purified you and chosen you above the women of the worlds."It is not the annunciation of birth of Christ.In Sura 19:17 It says one angel announced the Birth of Christ."What about Noah's son? According to Sura 21:76, Noah and his family is saved from the flood, and Sura 37:77 confirms that his seed survived. But Sura 11:42-43 reports that Noah's son drowns."Yes one son drowned the rest of the family was saved, your point?"Sura 7:136, 7:59 say Noah's flood took place in Moses' day. Did anyone tell Moses that?"7:136 says "So We took retribution from them, and We drowned them in the sea because they denied Our signs and were heedless of them."7:59 says "We had certainly sent Noah to his people, and he said, "O my people, worship Allah ; you have no deity other than Him. Indeed, I fear for you the punishment of a tremendous Day."what? it does not say that!"Sura 14:37, says Abraham lived in the valley of Mecca. The Bible says he lived in Hebron, Israel. (Genesis 13:18, 23:2, 35:27)"The Bible also says that Abraham went to the desert of Paran which is Mecca, and went to the land of Kedar. "Then God opened her [Hagar] eyes and she saw a well of water. So she went and filled the skin with water and gave the boy a drink. God was with the boy as he grew up. He lived in the desert and became an archer. While he was living in the Desert of Paran, his mother got a wife for him from Egypt. At that time Abimelech and Phicol the commander of his forces said to Abraham, "God is with you in everything you do. (From the NIV Bible, Genesis 21:19-22)""Sura 7:54, 10:3, 11:7, and 25:59 clearly state that God created "the heavens and the earth" in six days. But in 41:9-12 the detailed description of the creation procedure adds up to eight days."the word used in Arabic is "Thuma" which also means simultaneously, therefore it was simltaneously not 8 days."Suras 21:51-71; 37:97,98, says that Abraham was thrown into a fire [by Nimrod]. Nimrod and Abraham did not live at the same time. Muhammad was always mixing people together in the Qur'an who did not live at the same time. The Bible tells us Nimrod lived many centuries before Abraham."Wikipedia disagrees "The Bible does not mention any meeting between Nimrod and Abraham, although a confrontation between the two is said to have taken place, according to several Jewish and Islamic traditions."[1]It is also mentioned in the Talmud.[2]"Sura 6:74, says Abraham (called millata-Ibrahim in the Qur'an) father's name was Azar. The Bible says it was Terah (Genesis 11:27)."'he name given for this man in the Qur'an is Āzar (Arabic: آزر‎), though Arab genealogists related the name of Abraham's father as TāraM17; (Arabic: تارح‎). Even though the name is different in Islamic tradition to that in the Hebrew Bible, there is no doubt that the same figure is spoken of in both texts.' [3]"Sura 12:21ff, says the man who bought Joseph was named Aziz. The Bible says it was Potiphar."Sura 12:21 does not mention Aziz(http://quran.com...)[1]http://en.wikipedia.org...[2]http://www.jewishencyclopedia.com...[3]http://en.wikipedia.org...Then he keeps ranting on Islam and provides no proof for his claims on Muhammad pbuh, and says the Qur'an is false because the Bible disagrees with it...
