In a nutshell, here's the theological rationale for this techno-syncretistic "religious experience," according to Episcopal priest Matthew Fox:
Creation spirituality begins with the theology of original blessing instead of original sin. You came into the world as a real expression of divinity, and as something beautiful and yearning to connect with others, including with the Creator. The Cosmic Christ theology is also a big part of our cosmic mass. It teaches that the Christ, that is, the image of God, is present in every being in the universe. This allows you a much broader canvas in which to paint your worship.
