Ancient myth is a building block of humanity. We tell stories so that we can pass on information. As time moves on, the context for the stories changes or disappear, making it easy for them to be dismissed as “those old silly stories.”
We have dismantled those stories one by one thanks to science.
If you only consider the science and facts of a story from myth, then you gain some knowledge, while dispensing with the story. There was a reason the story had been carried on.
…You cannot see the forest for the trees.
