And even simpler than the exact tangible form of our bodies, is tangible form itself. The laws of physics allow matter to exist. Every molecule, every atom, gravitates together to give form. Pick up a stone, watch it fall from your hands. Gravity pulls it toward all the other stones.
Many people still hold a special fondness for certain elements, like sitting around an open fire.
Perhaps this dates back to the cave-dwellers, the primitive human Ancestors huddling around a flame merely to survive. Elementals burn deep within us, feeling that special romance in the warmth and light of a campfire, a household fire place, or even a simple votive candle. Many people also have a special fondness for water, the ocean, from which all life on Earth arose. Water was the source, life's birthplace. Water vapor rises from the ocean, crystallizes to form a raindrop, falls to the Earth, runs its course through life's rivers and streams, returning to the ocean, its source, to vaporize once again, perpetuating water's cycle.
