My biggest problem is how in the world did one book create dozens of religions and their wars. I believe most organized religions were corrupted long ago by governments to control the population.
A book cannot create war, as neither a gun can "murder" somebody.
They are neutral objects.
People create war, and people murder people.
In the case of the Bible, which I am assuming you are alluding to, it doesn't advocate the unjust wars that we see going on in the world today. On the contrary, it opposes them:
From In Defense Of A Gospel Of Peace
"The vision of peace was set forth in Old Testament. Isaiah looked forward to a day when the lion and the lamb would lay together (Isa. 65:25). Even when God did command war in the Old Testament, he laid certain restrictions, such as condemning those who sought out strength in modern weaponry instead of in the Lord (Isa. 31:1). Both the Law and the Prophets uphold the crossing of the sea in the Exodus as an ideal battle, where God delivered the Israelites even though they had no weapons (Ex. 14:13–14). Coupled with the concept of God’s grace and mercy (Dt. 4:31), God’s original design was peace for his creation (Gen. 1:31; 4:10), and his sorrow for violence in the world (Gen. 6:11), we see that the whole of the Old Testament does not put warfare on a pedestal. The cause and God’s sanctioning of war in the Old Testament is a direct result of human sin and wickedness and could have been avoided and was not the original plan of God.
"Then came Jesus Christ, the New Covenant and his wonderful message of peace and nonviolence, which did not nullify the Law or the Old Testament, but even raised the ethical bar higher. Jesus said "Blessed are the peacemakers" (Matt. 5:9). He instructed us against hatred and said it sowed the seeds of murder in our hearts (Matt. 5:21–24). He told us that instead of seeking revenge through "an eye for an eye" that we should turn the other cheek (Matt. 5:38–42). When he was persecuted and about to be crucified he did not fight back and even prayed for his persecutors (Lk. 23:34). He rebuked Peter for attacking the servant of the High Priest (Matt: 26:52). All throughout the New Testament were are taught about forgiveness, love and peace. Paul and Silas sang praises during their persecution in prison (Ac. 16:25). Paul wrote in his later epistles that he rejoiced in his sufferings (Col. 1:24) and that Christians should repay evil with good (Rom. 12:19–21). Peter, the man who earlier was rebuked by Jesus for drawing his sword wrote later that we should repay evil with a blessing (I Pe. 3:9).
"Yes, the New Testament does tell of a coming day of judgment where the Prince of Peace will lead the final battle (Rev. 19:11–21), but we must also remember that vengeance belongs to God (Dt. 32:35). Nowhere in the Bible did God ever allow people to go to battle without Him at the helm and nowhere is violence and strife outside of that realm condoned. Christians, on the other hand, are told to endure suffering and persecution, love their neighbors and enemies and do good to those who wrong them. The ultimate message of the Bible is that of love, grace and forgiveness, not warfare, destruction and hatred. The above interpretation does nothing to spiritualize or do away with the Old Testament or question the immutable character of God, only to draw attention to interpretive and contextual elements in Biblical study to show that the whole of Scripture, I believe, points to nonviolence."
