“To claim what you believe is to disbelieve in God.”
No. It is not. It is to believe that however God created the universe, He did it in a way that left the fossil record behind.
The fossil record is from the flood, not from millions of years of life. Where are all the human bodies? Interestingly how they never seem to find them.
If you say you believe in God, yet you disbelieve the Bible, you are an unbeliever, because you claim God cannot do as the Words says he did.
