As the ancient civilizations contemplated what substances made up the universe, most cultures came up with the basic four of Air (gas), Earth (solid), Fire (plasma) and Water (liquid). These were considered both matter and energy that sustained life. People contemplated these elements scientifically, philosophically and spiritually. How should we view these four things in the San Luis Valley?
AIR - Why is there air? To breathe? Blow up balloons? Make sure the Great Sand Dunes continue to reshape themselves? Carry the clouds across the sky? No instruments were available to determine the composition of air for the ancient peoples. They knew nothing about the gases that make up the air - nitrogen, oxygen, carbon dioxide, argon, water vapor and a few other assorted elemental gases in minuscule amounts. How did air come to be? Tough question, only that we instinctively know that it has mass when the wind blows and can make waves on water, blow dust into our eyes, bend trees.
