The Bible is the infallible word of God

While my opponent was praying that God uses him in a way that glorifies him, I was doing a little bit of research myself. I would first like to start off by asking my opponent a simple question: What makes you think that the Bible is in fact the infallible word of God? God himself never actually says them directly that the Bible was his word. Fallible imperfect human beings did. Nowhere in the Bible does it claim that all 66 books are God"s word or infallible. The doctrine of Biblical inspiration and infallibility was made up by Christian fundamentalists to create an artificial foundation for their faith. Also, I would like to ask my opponent, if the bible is in fact "incapable of error", then how are inconsistencies in the Bible possible? Here are just but a few examples of contradictions in the Bible: Mat 1:16 And Jacob begat Joseph the husband of Mary, of whom was born Jesus, who is called Christ. Luk 3:23 And Jesus himself began to be about thirty years of age, being (as was supposed) the son of Joseph, which was the son of Heli. Prov 4:7 Wisdom is the principal thing; therefore get wisdom: and with all thy getting get understanding. Ecc 1:18 For in much wisdom is much grief: and he that increaseth knowledge increaseth sorrow. 1 Cor 1:19: "For it is written, I will destroy the wisdom of the wise, and will bring to nothing the understanding of the prudent. " Mat 27:46,50: "And about the ninth hour Jesus cried with a loud voice, saying, "Eli, eli, lama sabachthani? " that is to say, "My God, my God, why hast thou forsaken me? " . .. Jesus, when he cried again with a loud voice, yielded up the ghost. " Luk 23:46: "And when Jesus had cried with a loud voice, he said, "Father, unto thy hands I commend my spirit:" and having said thus, he gave up the ghost. " Joh 19:30: "When Jesus therefore had received the vinegar, he said, "It is finished:" and he bowed his head, and gave up the ghost. " Now, if the bible is the word of God and is incapable of errors, then how is it that pieces of the bible can go against what may have been previously said in the bible? Does that logically make sense that two things can contradict each other and yet still be without error? If the Bible is true, then these conditions would be seen as real and verifiable outside of the Bible: The universe is only six thousand years old, dinosaurs never existed, the world is flat and the earth is in the center of the universe, the Sun goes around the earth, demons, invisible spirits, ghosts, holy ghosts, demons, angels, snakes, bushes, and donkeys, can talk, virgin birth is possible, god and jesus live in the clouds above, prayer has secret powers over this god, miracles and blessing do occur, invisible souls can either be saved or unsaved, depending on what a person decides to believe in their heart, the heart is the center of all thought and emotion, people can talk to god and jesus with their heart, there is no such thing as a brain, people can be raised from the dead, people can walk on water, water can be turned into wine, 5000 people can easily be fed with two loaves and two fishes, only invisible jesus can save invisible souls, diseases are caused by demons, science is of the devil, a person can live in the belly of a whale for three days and nights, a whales'stomach acid has no effect upon humans. Now, I'm sure that my opponent will say something along the lines of "You're not interpreting it correctly" . .. which is fine. But If "God" truly wanted to inspire people with this book, then why would he make it so difficult to interpret and understand? Why would "God" (the Being perfect in power, wisdom, and goodness who is worshipped as creator and ruler of the universe) make it so difficult for us to understand if he wants us to believe in him so badly? This is my opening argument, I look forward to my opponents response.
