I once had a house painter who tried to convince me the earth is just 6000 years old. I am a non-believer, I told him. This just fueled him more. So I told him I am a mongrel—father a Muslim, mother a Catholic, husband a Humanistic Jew, and me, just an earth-loving freak that likes to dance around bon-fires. That gave him even more gas.

Then I laid the bomb: I am a geologist.

That shut him up.

As Neil deGrasse Tyson posted today on Twitter:

If Noah’s flood carved the Grand Canyon 4400 yrs ago, then it nicely exposed rocks at the bottom, laid 2-billion yrs earlier.
