Washington Post:

To stand on the South Rim and gaze into the Grand Canyon is to behold an awesome immensity of time. The serpentine Colorado River has relentlessly incised a 280-mile-long chasm that in some places stretches 18 miles wide and more than a mile deep. Visitors to Grand Canyon National Park will encounter an exhibit titled the Trail of Time, and learn that scientists believe the canyon is about 6 million years old — relatively young by geological standards.

Now a few contrarian scientists want to call time out. The canyon isn’t 6 million years old, they say, but more like 70 million years old. If this order-of-magnitude challenge to the orthodoxy holds up, it would mean the Grand Canyon has been around since the days of T. rex.

No!  It can’t be the same age as T-Rex!

So much for the advancement of the flat-earthers!
