Science is ever evolving and is not always the answer to everything, nor does it always give the truth. There are still things that are unknown, may never be fully known or explained. Always approach things with questions and a touch of skepticism and be open to new learning and new knowledge. As, with anything involving us humans, there is NO COMPLETE TRUTH OR COMPLETE FACT. Nature, the world, the universe and life still hold magic and mystery and it is because of this magic and mystery that life is worth living!!
