Badger, you are aware that individual words have multiple meanings right?
also, the sun and moon were created until the 4th day (or was it the 3rd?), so the days before had nothing to do with timint the position of the sun in the sky..
...and the 7th day was an ETERNAL day, as interpreted by none other than the bible itself...meaning, the biblical interpretation of the duration of the 7th day is eternity and that interpretatoin is explicitly give and is not questionable
so, the lengths of the days were anywhere from undefined to eternal, or a mix of undefined and eternal
So we agree ascribing a "day" to God as the equivilent of 24 hours on earth is hubris and doesn't discount The Creation and Darwinism going hand in hand.
So how do you jive that with Genesis's account of God creating the many creatures of Earth essentially out of the firmament from scratch. Unless you are saying he created the animals in multiple "waves" to constitute each "day".
