I have seen many television specials aimed at children that explain the evolutionist viewpoint.
If G-d does indeed exist then He is likely as creative as the TV show producers. And the people of Moses' day were very intelligent, if not as technologically advanced as we are today.
I think they could have understood a lot more than He gave them. But I would not object to the most simplistic analogy being used. I would object to absolute falsehood.
Shalom.
At the time, yes they were intelligent. But the understanding of science was not what it is now, of course.
I don't see that Genesis takes any stand on whether evolution was the actual mechanism of creation. It doesn't really address mechanisms at all -- the point of Genesis is to emphasize that God is the Creator.
The way I see it, quibbling about evolution vs. ID vs. whatever else, is not much different from quibbling over the exact process of the Resurrection of Jesus. It may be an interesting topic, but ultimately it's completely beside the point.
