I think that sometimes when there is no proof either way, one should take some things at face value, to stop unnecessary speculations and arguments,
We can theorize or think that things may be a metaphor but because of the lapse of time we cannot say for sure if it is so or not.
For instance there is nothing in evolution to be found concerning the origin of the human species. There have been attempted frauds such as sticking arms onto ape skeletons in unnatural positions but scientists have debunked such attempts.
Where we find fanatics, who are the curse of lucid thoughts and humanity, we will find that they will always resort to heated debates without really saying anything constructive.
I give no references for this is only my opinion.
