You've provided evidence that peer-reviewed science often turns out to be incomplete, inaccurate, wrong, fraudulent etc. All true. But it is not the job of peer reviewers to assure completeness, accuracy, or freedom from fraud.
A peer reviewer reads a paper and make comments on it. That's it! They don't check primary data, they don't investigate methods, they don't interrogate scientists, they don't re-run experiments just to double check. They assist a journal's editors in editing--that's it.
The check on published scientific results is the scientific process itself, not the publishing process. Prominent results attract further investigation, which confirms or disproves the reality of the underlying phenomena. Again: that's not the job of peer review.
Do some people ascribe too much authority to peer review? Yes, for sure. IMO your comments in this thread are exacerbating that problem, not addressing it.
