My take on this is that someone back in biblical times found some fossil seashells or similar on a mountain and thought the only way they could have got there was if the mountain was once under the sea. Which of course it would have been, back when it was part of the seabed before getting uplifted into a mountain.
At the age of five, Skagra decided emphatically that God did not exist. This revelation tends to make most people in the universe who have it react in one of two ways - with relief or with despair. Only Skagra responded to it by thinking, 'Wait a second. That means there's a situation vacant.'
