This line of understanding works for you, fine, but you are not adequately arguing against the proposed counterpoint, you are lancing a sort of strawman. In case you missed my earlier post, there are not only two polar opposite positions to this, truth or lie, fact or fairy tale. There can, and to me "is", a position of more relevant "truth", an even "better wisdom", to be found in the words of Genesis.
We understand your position. Your wholesale rejection of the consideration there are third, fourth, maybe more explanations is stubborn, no less offensive. It is not a "fairy tale", God did not lie. Genesis is pertinent, even more, integrally important, to all of the rest of the inspired subject matter presented in the Word. It simply is not, to me and others, all to be a literal understanding as a news report or straight-forward mathematical equation. If you're going to argue against a point, argue against the point being made, not attribute qualifiers so the concept is more easily defeated.
