Why do people still teach the ideas of Darwin, since Darwin didn't mention genetics in any of his writings. We now know genetics is an underlying cause of many of things in life and evolution? That was a huge oversight on his part. Darwin's book did not even do a solid statistical analysis of his data? If anyone presented their life science data that same way, it would never be published.
The reason we still teach about the ideas of Darwin is because he played a key role in the history of biological thinking. He helped to lay the foundation for modern thinking. When we learn about the present, in the context of the past; Darwin, we can better anticipate the future; two point allow us to draw a line.
The same is true of the bible. Like Darwin it may not be up to date to the ideas and protocol of modern times, but it still provides a foundation by which many of the ideas of the present appeared and can be extrapolated to the future.
Those who wish to rewrite the past, are trying to create a trick line to the future; the future they wish it to be. Those who don't learn from real history, end up repeating the mistakes of the past, and waste everyone's time reaching the real future.
