The Bible, and other religious books, are an entertaining series of stories that describe in words the mind of one self aware organism, namely Homo Sapien.
These were written by humans to answer the most difficult questions humans have, and they were written at a time when humans had no real understanding of the universe around them. They were a simplistic answer to complex questions in a relitively simple period of our
development.
Historically it is the Bible that has adapted to our growing knowledge over time. If it were a book of truth and the word of God, our growing knowledge would corroborate the Bible and strengthen the words found therein. For a believer, God gave you a
brain, you need to think and question the assumptions and writings of others, that's how we advance as a species.
