Many people have commented that science changes all the time. Some people have said that even Category 1 (C1) 'Proven' Science (as I have defined it) can change.
For now, there are only 3 major points of science that I am interested in. I find it very hard to believe that any of these will change. The science behind these facts is substantial.
F1. Age of the world is significantly older than 6000 years
F2. Many intelligent humans living all over the world 10,000 years ago.
F3. No global flood, or anything close to it.
These three facts by themselves, are enough to force large parts of the first 11 chapters of Breishis to be one of the following Theories:
T1. Nes / Nisayon
T2. Myth / Moshol
T3. Not literal / Imprecise / Darshen
Personally, I haven't seen anyone do a good job at T3 while still conforming to F1,2 & 3. I would be very intersted in someone doing that. 'Yom' meaning 'Period' is only one small piece.
