How do your propose teaching the Bible without any discussion of primary events in the Bible? The act of creation, seas parting, men rising from the dead, global floods wiping most of humanity from the planet, etc., are all core elements of the Bible and mankind's existence on the planet.
1. Creation. The Hebrew uses a word that signifies a beginning and end points of time. It is often--but not by any means always--used to signify a day. The same word can cover eons. Students can decide for themselves whether they believe God blinked his eyes like a genii and creation appears--or whether the different segments of creation took eons.
2. Seas parting: Many things have been suggested, among them low tide.
3. Rising from the dead: Yeah, we have stories of people doing that today as well. Books are written about them.
4. The Bible did not use the word for 'planet' or 'globe' in the account of the flood. It used the word for 'land/earth/dirt'.
These are all basics everyone should already know. The fact you don't is why I think teaching the Bible would be an asset to society, not a detriment. Even in the first, any budding atheist is quite free to believe evolution may well have occurred without a Supreme Being.
