Utter bunkum. Science has nothing at all to say even about dualism let alone about God because it (intentionally and by convention) only speaks to the material, while the "rationalizations that support the concept of God" have never been mere questions about how the material has changed from state to state.
Which definition of God have you heard that includes there being something that you can actually prove about it? Everything I've heard is inference of causality. X, therefore God exists because Y. Y is never objectively universal, X is often flimsy and the connection is never explained or defined.
The constant droning about imaginary tea cups is a bare faced straw man
Thus why I said "attempts". Just like everyone carrying the idea of God doesn't have a united front, there are people coming at it from all sides with varying arguments of varying quality. Doubting the existence of a tea pot doesn't disprove God, but it's supposed to illustrate that you don't have to assume that God does exists just because someone holds it on faith. Where it really falls down is that you actually could find the tea pot, whereas no one ever produces anything that unambiguously, to widespread agreement and without fail would prove the existence of God.
The way people "believe" in infinite universes is probably fraught with misuse too, but if there was no way of holding a working hypothesis in your head temporarily in order to work from it to build a model that could be tested, there would have been a lot less scientific progress.
