God created light on the first day of creation, but it wasn’t until the fourth day that He created the sun, moon, and stars. There was light three days before there was what we now know to be the source of light. It seems to me that Genesis 1:14 disproves this long Earth theory. This account says the earth existed before God created the sun, moon, and stars. That shoots evolution in the head. Also, all the old age Earth theories have animals dying prior to Genesis 1 and speculate that’s where the
fossil records come from.
