However, Pantheism goes further, and adds to atheism an embracing, positive and reverential feeling about our lives on planet Earth, our place in Nature and the wider Universe, and uses nature as our basis for dealing with stress, grief and bereavement. It's a form of spirituality that is totally compatible with science. Indeed, since science is our best way of exploring the Universe, respect for the scientific method and fascination with the discoveries of science are an integral part of World Pantheism.
I'm an atheist and I see no reason to "go further" than my lack of belief in claimed gods (or to redefine gods) in order to have an "embracing, positive and reverential feeling" about my place in the world, or about any other aspect of my life.
Why go beyond straight atheism?
Does atheism need sexing up? As such, atheism answers only a single question: is there a creator God, or not?
I disagree. To many, probably most of us, atheism is simply the lack of belief in any proposed deity. It is not an answer to an illogical theological question ("is there a creator God?"), or statement of faith, or a belief system, or even a world view in any significant sense.
Yet after you've reached that initial "no God" answer, all the other important questions in life, all the options for mental and emotional wholeness and social and environmental harmony, remain open.
Important questions for which, again, donning a vague label based on redefining "God" is unnecessary to our efforts in trying to answer. Efforts, by the way, that should duly be credited to such long-established approaches as humanism, existentialism, psychology and many other specialised and different ways of dealing with these questions.
