Materialism’s Worldview of a supreme being:

Materialism denies that God exists.  It also denies the existence of angels, demons, heaven, hell, or anything of the spiritual realm.

The supreme being, to Materialists is humanity.  Each person becomes his or her own god by default.  There is a tendency, in Materialistic writings, to also deify things like evolution, natural selection, nature, the universe, science, etc.  Often, we find the odd combination of pantheism or Mother Nature beliefs among Materialists—which seems inconsistent, but the real reason for materialism is to say: “anything but Jesus.”

Materialists define the word, science, as beginning with the “axioms” of Materialism, Naturalism, and Uniformitarianism.  Rationalism is needed to make such a definition.
