Worship of sun in Aryan vedic rites always felt like an ancient ritual to please the elements. Looking deeper, it seems that at some subtle level all the energy and matter work very closely (every living thing has derived energy from solar energy) so at some level gross expression of respect and gratitude is a form of communication.
A flower that I had floated in a crystal bowl draws its petals inwards in the night even when it is not attached to the plant and is away from sunlight. How come the cells of this flower detect the sunset? What is the necessity in a plucked cosmos to draw its petals at night? Maybe cells of our body, with the proven fact that each cell has memory and gray matter, communicate with the source of energy. It is just a thought that consciously aligning our mind and spirit to this subtle communication , brings us into balance and harmony with nature and elements. Maybe this was the reason that all the ancient religions had rituals where they revered the nature. Have also observed that when we communicate the need to be healed to nature, it is herd by some intelligence and works out somehow. When I venture out in sun, I sens its rays and feel that they cleanse all negativity, it seems we should not fear elements but know that they are an integral part of our being, this way the elements work to keep us disease free and young. Dunno, came to me as I was watching sunlight bath treetops in mellow pale glow.
