if you're an atheist you can't believe anything that science doesn't say.
Atheism is simply a position about the existence of [a] G/god, namely that there are none.
An atheist could very freely reject literally everything science says about anything, and could still be an atheist--simply because they simply don't belief in the existence of a divine power of any sort.
In the same way, belief in a divine power of some kind, or being religious of any kind, does not render someone opposed to science.
There are scientists who are theists, scientists who are atheists, scientists who are agnostic, scientists who are deists, and scientists who can probably be described as apatheists (they simply don't care one way or the other).
And there are people who fit all those categories who are scientifically illiterate, or who reject science, etc.
The two simply aren't related.
The idea that atheism and science are linked, while theism and science denialism are linked is more to do with a cultural myth that we continue to perpetuate. And no single "group" is to blame here. I've seen devoted Christians and other religious people perpetuate this myth, and I've seen atheists perpetuate this myth. Because it's a myth that has somehow become baked into our culture, and which popular media expresses and the whole thing becomes like Ouroboros eating its own tail, a self-perpetuating feedback loop.
Where this ongoing myth becomes more than just wrong, is that it actually has a measurable impact. As it influences identity. E.g. "I am a Christian, and therefore I cannot accept evolution, because only atheists believe in evolution" or "I am an atheist, and religious people are all closed-minded science deniers".
Recognizing that religious or various metaphysical questions are of one kind, while questions about observable, testable reality are of another kind is important. It frees us up to have better conversations, and to decrease misconceptions.
