A letter April 12 seemed to disparage the professional science and understanding of how Earth's geology (including the Grand Canyon, etc.) has occurred over deep time and the evidenced facts of evolution of life on planet Earth (Reader's View: "With faith, no need to fret over climate").
One can achieve advanced degrees in Earth science: geology and evolutionary biology; around the world, for a century or more, many tens of thousands have done so.
But to some it is still more believable to think snakes can talk, people lived to be 600 and 900 years old, and that being swallowed by a whale for days and emerging unharmed is more credible. They need to grow up mentally.
