Exactly right. The word used actually means "a unit of time." It does not actually define which unit is used. The word is so vague it can mean any span of time from one second to infinity. If the earth did not exist, you can't measure the span of a day of revolution let alone a year of orbit. Anyone telling us it means a literal seven days, IMOHO, is a mouth breathing moron. It clearly means some nebulous span of time like era or epoch. > Then God said, ‘Let there be light’; and there was light. And God saw the light, that it was good; and God divided the light from the darkness. God called the light Day, and the darkness He called Night. So the evening and the morning were the first day.” It plainly reads it's a metaphor and not a literal 24 hours. As we've just established, there can't be 24 hours as there is no orbital period from which to derive. It's a metaphor for day (daylight) and night (darkness). This took part during the first epoch of time. > “Then God said, ‘Let there be a firmament in the midst of the waters, and let it divide the waters from the waters.’ Thus God made the firmament, and divided the waters which were under the firmament from the waters which were above the firmament; and it was so. And God called the firmament Heaven. So the evening and the morning were the second Day [Epoch].” If we substitute for what it says in the first epoch, it reads: > “Then God said, ‘Let there be a firmament in the midst of the waters, and let it divide the waters from the waters.’ Thus God made the firmament, and divided the waters which were under the firmament from the waters which were above the firmament; and it was so. And God called the firmament Heaven. So the evening and the morning were the second Epoch of light.” Again, it clearly draws upon the metaphor established in the first epoch. So on and so on...
