How can there be 24-hour days before the sun was made on the fourth day?
A viewer asks how the creation days can be 24-hour solar days when the sun was not created until the fourth day.
Answer
They are not solar days; the sun simply takes over the job on the fourth day. In the creation week there were two lights. On the first day God said, let there be light, and that great light had to be about 10,000 times the size of the sun, because it had a much bigger job to do. In the beginning the earth was in the middle of the deep, a Hebrew word for very deep water, and with no light there is no heat, so you have a giant ball of ice, about six billion miles in radius, farther than Pluto. God made the firmament to separate the waters, and then, as ten passages of Scripture say, he stretched out the heavens, changing the firmament from a solid that held up the water into the transparent expanse we see, so it could hold the sun, moon, and stars on the fourth day. As soon as the great light was made, it began revolving around this ball of ice to melt it, and as it revolved it dissipated into outer space, which is why Scripture still speaks of that light as existing. That revolving is what gave you the first 24-hour days, before the sun took over the timekeeping on the fourth day.
