This episode recaps the resolution of the apparent problem of the source of light described on day 1 and day 4, noting particularly how an appeal to God as the source of light on day 1 makes little sense.
Are the days of Genesis 1 24 hour days?
One of the major disputes between science and Genesis 1 potentially centers on the interpretation of the Hebrew word "yom" or day. There are 4 literal meanings of the word "yom," one of which is an indefinite finite period of time. This possible meaning would resolve the apparent chronological dispute between Gen 1 and science.
