It makes sense to me from what I read and see. If that is the gap theory....then that is how it looks to me.
Could God create it all in finished form at once. I suppose so, but did He?
We don’t have to all agree on this.
Because some like me think that the earth is older than 6,000 years does not mean that we believe in evolution.
Evolution is ridiculous.
The gap theory has been debated extensively. You can find many arguments both for and against it. I am keeping an open mind. I still prefer the argument that God created a fully mature universe. It just looks billions of years old.
