Petrified fossils are millions of years old, not 6,000 and to assert the contrary accuses the Creator of lying through the fossil record
God being the deliberate Author of Time and all things we lack the Wisdom and Authority to accuse the Him of anything. Accept his Authority and Power or reject it.
God Almighty is the single Being who can truly say: “Are you going to believe Me or your lying eyes”.
I will believe God. I've had enough experiences to know not to trust my own perception.
The problem is that I don't believe, and nothing in the Bible tells me, that God created rocks in the shape of bones and trees just to mess with my head.
If you choose to think Genesis says He created the whole universe 6,000 years ago, you're free to do so. I know it doesn't say that.
