Yup, it's all about timescales. Fact: in large animals like humans, with long lifespans and low reproduction rates, evolution takes thousands of years to fixate any change in the population. That's about the time
human civilization existed. In those few thousand years, we went from primitive tools to germ theory, vaccines, rocketry, etc. (and most of interesting developments happened in the last few hundred years; we're riding an exponent here).
Evolution for humans just doesn't matter, because at this point, we're doing meaningful changes to ourselves and our environment at a rate faster than it takes for a human to reach reproductive age. We didn't wait for evolution to adapt us to colder climate, fix our eyesight or change melanin levels; we just developed clothes, glasses and sunscreen - which also made these features not influenceable by natural selection pressures. And whatever mutation happens that doesn't kill a person, we work around it socially or technologically - which means its impact on reproductive fitness is usually close to zero. Biological evolution is no longer the force driving the shape of our species.
There is an evolution of humans happening, but it's social and technological, not biological.
