Zaccheus:
You are trying to apply a level of precision that was not intended, was not needed, and that people normally would not apply in such a context.
It is not just the lack of precision, but that at the same time, other cultures had a much better approximation. To say that the simple people, who wrote those passages did not know any better, nor did they care - would be perfectly acceptable. But not the word of God.
You can’t have both ways. Either the Bible is the word of God, or it is written by some people, who did not know any better. Of course the Bible could have said that the circumference of the circle is APPROXIMATELY 355/113 times the radius.
Of course that was just one example. The discrepancies between the bible and reality are far too numerous to mention. The so-called creation of the first human couple cannot be accepted as literally true, and yet, many apologists argue otherwise.
To sum up: until there is NO “Catholic Annotated Bible” which would enumerate which verses are literally true, and which are allegorical, you are not in the position to argue. There are far too many verses which are ALLOWED to be taken literally or allegorically at the “whim” of the apologist. And THAT is the unforgivable problem.
