Gen 2:4 insists the translation of "yom" be indefinite period of time. You can't have a 24 hr day without the Sun. It wasn't created until the fourth "yom".
You are misinterpreting the Bible if you think that the Adam segment pagan myth is related in any way to the scientifically more accurate Gen 1 account.
I believe the Creator of the sun knew that He would make days be 24 hours!
I am not trying to tie anything together, I am in no way affiliated with AIG, I think their website is interesting, but I prefer to simply study God's Word in context. When you pull a verse out of context( Gen 2:4) of course it can take on different meanings. Look at the word in the whole context of the chapter.
If I am misinterpreting the Bible, I AM DEFINTELY NOT THE ONLY ONE. WE HAVE A COUNTRY FULL OF BIBLE COLLEGES AND SEMINARY SCHOOLS THAT TURNING OUT STUDENTS, WITH MASTERS/DOCTORATES THAT HAVE NO CLEAR UNDERSTANDING OF THE BIBLE .
