[In biblical mythology,] God sent humans to write the bible because his servants can relate better to humans since they are humans. [Unfortunately, this literary work fell far short of helping humans relate better to the concept of the xian god, due to advocating violence, hatred, and intolerance. The numerous errors didn't help either, because it proves the books were not inspired by the creator (for example, bats are birds, Earth is flat and stationary).]
