"Probably, so far as l know, there is no professor of Hebrew or Old Testament at any world-class university who does not believe that the writer(s) of Gen. 1-11 intended to convey to their readers the ideas that (a) creation took place in a series of six days which were the same as the days of 24 hours we now experience (b) the figures contained in the Genesis genealogies provided by simple addition a chronology from the beginning of the world up to later stages in the biblical story (c) Noah's flood was understood to be world-wide and extinguish all human and animal life except for those in the ark. Or, to put it negatively, the apologetic arguments which suppose the 'days' of creation to be long eras of time, the figures of years not to be chronological, and the flood to be a merely local Mesopotamian flood, are not taken seriously by any such professors, as far as I know."--Professor James Barr, (1984) former Regius Professor of Hebrew at the University of Oxford.
FWIW (according to my limited research), Professor Barr, like you, rejects the idea of a six day creation, but is honest enough to admit that the Hebrew cannot be twisted to infer that these are ages or that the Noahic event was anything other than a world wide flood.
It is clear that if anyone is force fitting the scripture to fit their pre-conceived notions it is you.
It is true that the story reads 6 days and that it does give the impression of normal days.
It is, therefore, legitimate for that interpretation to be one of the possible interpretations that should be investigated.
Case closed.
Sorry, but here is a list of quite a few world-class scholars, apologists, theologians, etc., who disagree with that statement:
Notable Christians Open to an Old Earth Interpretation
In fact most of these people are well known for the defense of the literal Bible, contrary to the accusations that people who support local flood/old earth don't.
Also, the statement "the figures contained in the Genesis genealogies provided by simple addition a chronology from the beginning of the world up to later stages in the biblical story" is perhaps one of the most unscholarly statements I've seen in awhile. Hebrew scholarship proves without a doubt that, especially the early chronologies, cannot be and were never intended to be added up.
