Why Trust The Bible if it Was Written by Men?

A common claim among skeptics of the Bible is that it can not be trusted as it was written by men. This is quite a strange claim, primarily as all books are written by humans. By this logic, every document could be seen as uncredible as it was written by people. From articles from NASA to lectures from your favorite teacher. Is two plus two not equal to four as I, some random person on the internet, affirmed it was? The point being, just because a human wrote something does not mean it is uncredible.
