The alcohol wasnt what made beer safe. Beer was safer than water because to make bear one must use sterile water. So beer at least started out sterile/boiled before it went into the barrel.

This is complete and utter nonsense. The water used in beer often had bacteria (and other stuff) but to brew beer you must mash, at 65C for an hour or more, which pasteurizes the beer. Hops protect the beer against bacteria, and the yeast also makes it hard for other organisms to multiply in the fermented beer. Alcohol is one of those ways, but only one.
That is modern beer, the stuff made by people who know about bacteria. Prior to modern knowledge, beer recipies were based on trial and error. Boiling the water first avoided many spoilation problems that, today, we know how to prevent through other means.
Again this is stuff you're just inventing because you don't know better.

You have this backwards. Boiling or near-boiling the water is what's nearly universal now. It was much less common in the past.

Correct. However, all beer is mashed. You don't get beer without it. That's a one-hour 65C pasteurization at the very least. As far as we know, all European beer from the stone age until now was made this way. So you can take this part as ordained by the gods of chemistry. So no matter what you do about the water initially, the whole thing will be pasteurized afterwards.
There are still people today brewing traditional beer from recipes based on trial and error, with zero input from modern science. Some of them start with a mix of cold water and malts that they then heat in the kettle. Here's an example of me visiting and brewing with a guy who does exactly that https://www.garshol.priv.no/blog/409.html
If you want I can make you a map of where in Scandinavia and the Baltics people used this method the last 100-200 years. Before that people often didn't have kettles, and so (as far as we know) the water was not heated before brewing (long story exactly why we think so).
I think you misread the comment you're replying to.

AFAICS you're agreeing with this, so "complete and utter nonsense" seems a bit harsh
This was the part I was referring to: "Beer was safer than water because to make bear one must use sterile water."
I agree I should have quoted that to be clearer.
