Have humans always instinctively bathed or did they come up with the idea after settling?

I hope someone’s able to answer this because as far as I’ve read African and South American communities (maybe others, idk) were repulsed by the Europeans stench. So was it a climate, or even cultural thing (cause it seems like Europe’s lack of baths was due to a cultural belief)? I’m really curious
