• Motherfucker how long do you think humans have been around for? Okay, sure, soap has been around for like 6k years, wow, such a long time. Modern humans have been fumbling around figuring shit out like an untrained ai model for the last 60k-160k years. Quick math shows us that for somewhere between 54k and 154k years of our history as a species, no soap. MILLENIA!

    Drinking water: you’re making a distinction between clean, as in unpolluted by chemicals and other substances, and cleaned drinking water, which has been processed by humans to make it fit to drink with a lower risk of causing illness. Clean water has obviously been around for eons, but cleaned water, as I believe OP was describing, is a much more modern concept.

    Showers: “try skipping a shower for a day”? Motherfucking neckbeard no, shower every fucking day. Try it, people might find you somewhat less repulsive until you open your mouth.
