Sol is the life-giving star at the center of our Solar system. Sol (our sun) literally provides all the energy that animates life on Terra (our earth).
The energy an eagle uses to flap its wings comes from Sol. The energy an ant uses to carry a leaf comes from Sol. The energy you use to read and understand this text comes from Sol. Ants carrying, eagles flying, people thinking ... none of these would exist if Sol didn't send its life giving energy our way.
Without Life, the energy from Sol simply bounces off the planet. Life literally collects the energy Sol sends to earth, and stores it up for future use. Plants take energy from Sol and convert it into denser, more storable forms. The sugars and fats that our bodies burn are little pools of energy that originally comes from our sun. Ants carrying, eagles flying, people thinking ... none of these would exist if Life wasn't capable of storing up the energy Sol sends.
