The Sum of Awe said:
If the Bible's story Genesis was about how God created mankind, why isn't Evolution in the Bible?
Just as the Bible doesn't contain anything about geometry, physics, chemistry, biology, medicine, earth science, geology, (real) astronomy, and the list go on.
The Bible, let alone Genesis, is not a book of science.
At best, it is a book of theology, and the Genesis contained the narrative myths. The Genesis comprised of the creation myth and the founding myth (ancestor or founding father myths of the people, like the Hebrews or Israelites, in this case).
Both of these myths are similar to other ancient non-Judaic myths of other civilisations and religions. And like other culture or civilisation of that time, there knowledge about how the world work was very limited, and somewhat primitive when you compare it to modern civilisation.
But getting back to evolution. Evolution is science not theology or a religion. And it would be out of place in the Bible, wouldn't you think?
But you are probably thinking that since some religious folks say that God would be all-knowing and all-powerful than God would know all about evolution so it would have been written into the Bible. There is no evidence of such divine and superior being except from hearsay by those people who claim to be "prophet" or "priest" of God.
And like I've said before about the Israelites being like other people of their time, with regards to learning and to their religion, I would not think they could possibly know about evolution. Even then, there understanding of the human anatomy were no better than anyone else at that time, but you expect them to know the process or mechanism of evolution?
