Hint: in Hebrew, the original language of the Old Testament, the word "day" can refer to an undetermined period of time…
You can find people who believe anything, and it can be difficult for a non-Christian to sort through Christian writings and beliefs for the orthodox view. Heck, it's difficult in the best of times even for Christians, and these are not the best of times. There IS an orthodox view, however.
The orthodox writers are spread across denominations, but they all refer to and expand upon each other's thoughts. They also stand the test of time-- if a Christian writer is still being read by Christians in many denominations decades or centuries after his or her death, you can bet that those writings reflect the orthodox view. False doctrine falls by the wayside over the years, but that which is true remains.
If you're interested in who those orthodox writers might be, I would be pleased to post a list of those I have read.
Oh, and by the way, doesn't it strike you as profoundly illogical that the King James version fanatics deny the biblical texts in the very languages that would have been known to and studied by Jesus Christ? The King James version is, in my opinion, the most beautiful language, but I know that it is not necessarily the best translation. However, that has no bearing on the meaning of the word "day" in Genesis-- the KJV text uses "day" just as the modern texts do, and in English, the word "day" can refer to an era.
I find this whole issue exasperating-- in my day, young people studied the English language in school so that they would become literate adults and not have these silly sorts of arguments. ;)
