"No scientist,or group of scientists,will ever be able to prove...or disprove...the existence of God."

And that's by definition. An infinite being cannot be "proved" by finite standards or methods.

Scientism is very odd. “We study X. Nothing outside X exists.”

How would they know, since they don’t study anything outside X?

They could reasonably say, “We study X. We do not know what outside X exists and have no opinion of it.”
