I meant "materialism" as in the philosophical sense, like positivism or scientism and unlike Platonism.
Sorry if these words are unfamiliar to you but they are pertinent to the discussion.
If you believe that science is conceptually complete, that "science" is interchangeable with the term "rationality", then you are indeed a materialist. This philosophy is really inconsistent with all the major religions.
Conversely if you are sympathetic with any form of Platonism, then I would ask you why the idealised concept of God seems so bizarre to you.
It's up to you whether or not you engage meaningfully...I'm just trying to inject a bit of rationality into the discussion.
