Don’t appeal to evolution, evolution is weird. Evolution just does whatever survival says. If we can survive drinking milk, evolution is cool with it. But evolution is weird, evolution will be all like “You like cows milk huh? That’s cool, have you considered shrinking down and losing your brain and most internal organs to become a nipple latching milk parasite? No? Ok, I’ll ask again later.”
Water? The thing adult humans evolved to drink.
A good chunk of human adults also evolved to drink milk, my dude.
