This is partly true, it did start in NAZI Germany. But in general, most of the ancient world, whether europe or the near east, revered fire and the sun because it was viewed as the source of life-giving energy. And part of NAZI ideology was a desire to return to ancient practices and cultures of Europeans (although ironically the ancient Germans had relatively little cultural similarities with the ancient Greeks); Hitler believed Christianity, which came later, was well-meaning but unsustainable.
