First of all, science does not permit "proof" of anything, only evidence for and evidence against. One compelling piece of evidence for spread without masks, with no touching, greater than six foot spacing and a large indoor space is the church choir event. There are more but that one is a good example. Some less substantial evidence for masks stopping the spread is the Missouri beauty parlor. There are other explanations such as the interactions being too short to allow spread.
You are welcome to provide evidence that masks do not work.
Seeing that a large percentage of new infections are among the “woke” millennial population, who happen to be the most compliant virtue-signaling mask wearers, I’m guessing those statistics are nonexistent.
That's not evidence of anything other than you don't like millenials. I see a lot fewer millenials with masks than older people.

Well that’s convenient. I’m suppose to provide evidence to prove a negative.
Well you’re welcome to provide evidence that those choir members would not have become infected if they HAD been wearing masks.
