It literally doesn't, and cannot, say "nope". It wouldn't be science if it passed any judgement on Religion, because it literally cannot provide evidence to support or contradict Religion.
> Religion should be declared a myth
That's your opinion, which is fine. I share your opinion too, but that's all it is.
As an aside - from observation, the use of "Science!" has become it's own sort of religion. Blindly offering "Science!" as a reason something is true or untrue is totally the antithesis of actual science, and unfortunately is becoming far too common.
I would suggest that every mainstream religion is so full of holes after you reject such claims as to have little remaining value. I have not personally evaluated thousands of individual belief systems due to lack of time and energy but evaluated enough to have developed the theory that there aren't any good ones among the philosophies that would self describe as religions and especially those that make supernatural claims.
It's the religion cult the accountable one who need to probe their magic.

No, Unicorns are better. And magic. Magic explains everything.
- improbability
- lack of proof
- zillions on contradictions on their own manual
As I said, the burden of proof (God existence) it's up to the believer, not mine. Science says "nope", or unprobable enough clashing with near all common logic facts to not being declared a myth.
