"If the bible is the word of god, why wasnt it given to man the minute he was created, if god knew all things?" (sic)

Because since the beginning, God has revealed things little by little as the world at large is willing to listen to more of what he has to say. It is known historically, that the Bible was not given to us by God in one lump sum. Instead, starting with Adam, each prophet wrote things down, and they were compiled together by prophets and leaders that came later.
