      Human stomach acid is as low as PH 1.5

      We are descended from scavengers

      The acid we make is PH 0.8, it goes to 1.5 when mixed with the other gastric juices

          I presume it’s because some pathogens are adapted to us, or it’s because of our changed diet since the agricultural revolution 10k years ago at most, or our population density and food production and transportation system causes greater exposure to pathogens, or done mix of all those and probably more

          The modern world is pretty complex

      There are sure to be tradeoffs which would explain why not every animal have evolved similar stomachs. It’s probably expensive energy wise to maintain that acidity. It probably also makes it hard to maintain a healthy gut flora. Also imagine the burn if you vomit up stomach acid with pH 1.0

      In the game Mass Effect, the Krogan race has all these “backup” organs. They pretty much evolved to become incredibly resilient.

      But they also become alpha douches.

      Either way, I love those little guys.
