Teeth are the proof that God doesn't exist, no celestial being could be dumb enough to create teeth which if not brushed regularly with semi-annual dentist checks rot because of.... foood.

There's a difference between the food that's been eaten over the past thousands of years and the food that we all eat today. I suppose if you look at this the right way, it's another argument in favor of evolution. Teeth are optimized for hunter/gatherer diet and lifespans. Doesn't matter if your teeth rot out by 50 if you die in your 30-40s

30-40 is plenty if you’re having offspring by 13-17 and seeing them to the same age. Teeth need not last any longer.

Only the type of food we eat in an “advanced” society

And what food do we eat in advanced society, titanium?

I eat meat, vegetables, some sugary things ofc but they had honey back then. Honey also rots teeth.

People "back then" didn't have access to an industrial quantity of honey

Regardless, most people in the westen world dont eat like you. Most of their calories come from ultraprocessed garbage (look up the nova food system)
