The Bible says in the first day God says let there be light and there was light and on the fourth day God created the sun and the moon paving way for day and night.Does it mean that there was no day and night during the first three days of creation?
The account of each day of creation ends with “And there was evening and there was morning … “ To me this says that each day was defined by a period of darkness followed by a period of light. The key that unlocks the mystery you’ve described lies in the Hebrew language. In Genesis 1:3 the Hebrew word for light is “owr”. In Genesis 1:14 the word is “mowr” which means light repository, or literally chandelier. On day four God in effect gathered the light of day into the Sun and the light of night into the Moon and it’s been that way ever since.
