The problem with religion is people don't know how to separate the myths and legends from the moral teachings and guidelines. This is especially true in the Abrahamic faiths, and specifically Christianity. Here-in lies the problem:
All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness...
2 Timothy 3:16
Lots of Christians take this passage to mean that God dictated to the writers, and that every last word in the Bible is meant to be taken literally, as if God had written it. They leave no room for argument that the writers were simply human beings that were religiously-inspired to write these books, which would leave the Bible open to interpretation.
Thus, despite overwhelming scientific evidence to the contrary, we have a large number of people convinced that the world is no older than six thousand years, that
Homo sapiens sapiens just popped up one day, that in the space of a month Egypt was afflicted with several-years worth of catastrophes, and that a human being rose from the dead. They get so hung up on taking every word literally that even when scientific findings
can be reconciled with a less strict interpretation, they refuse to accept. Science provides evolution as the answer to how, and allows religion to be the answer to why.
