But if we're going to examine these texts critically, as products of their historical context, despite "yom"'s possible other meanings, it seems kind of pointless for the person who wrote the texts to refer to *six* periods of undefined length. It seems much more likely the original authors had the literal meaning of "day" in mind. Then again, I'm not a biblical scholar or anything; it just seems pointless to refer to a vague period of time and multiply it by six. It's like, there's no information content in that extra piece of info.
I don't really see the need to read it literally, and 7, (six days of creation plus the day of rest) is an important symbolic number in the Torah, and I think this is part of the reason for this division.
Also, I can't remember where, and whether it was in the Quran, but I've heard a Muslim authority of some kind say -- or write -- once that the universe was *not* created for us and that it is arrogant to think so. I'm too tired to verify this now, but I think I've seen it somewhere.
I guess you could infer that from the Qur'an too, and it's a respectable position, but I don't think there's any unequivocal statement in the Qur'an to that effect.
Are you a Muslim, by the way?
I'd say I'm more of a wishy-washy theosophist with some sympathies for the Abrahamic and Dharmic religions.
