What are you arguing? That we're can't know anything ever? That's not very useful in any kind of practical sense.

Figuring out what's going on from statistics isn't that hard if you understand how those statistics are being collected.

But they sure beat whatever you, a single person, happens to see with your own eyes. Your personal experience is an almost infinitesimally small random slice. It's just not statistically significant.

Statistics may always have error bars, but the errors bars around your personal sampling of one will always be incomparably larger.
