Unsuccessful again in persuading a Bible literalist the Earth is not 6,000 years old. At first, I thought I was doing well. I put aside the issue of evolution because that's was too loaded. I focused strictly on geology and the evidence that shows our planet is very, very old. I used canyons because any one of us can go to a canyon and count the strata -- geology is right there in front of you, on a literal basis.

No go. The fundie said that The Flood caused all the great canyons. I suggested she read a geology text paying attention to the difference between slow erosion patterns and the effect of violent, cataclysmic events. Don't know whether she will but I doubt it.

So, I wondered if some here might have some fresh suggestions for the next time I go into one of these discussions. (I also brought up carbon dating and the length of time it takes for light to travel through the vast distances of space -- those didn't seem to make an impression.)

What other clear, simple, easy-to-understand evidence would you point out if you wanted to demonstrate our planet is more than a few thousand years old?
