Yeah, I used to date one and I took my lumps. Seriously, what's to say the carved stone relates to other artifacts at the site? Unless there were associations that can definitely place it at 30K it's entirely possible it was left there much later than postulated. Sites that yielded knappable quartz minerals were popular with tool and point-makers during the entire stone age and drew many different visitors over long time periods.

Yes, there is good reason to be a bit skeptical on the dating.

In China and Japan where the majority populations usurped civilizations that predated them. There are strong social/cultural/political reasons to distort facts/dates.

Even the most transparent frauds are often go on for years, take the case of Shiniichi Fujimura in Japan:

Japanese paleolithic hoax


Of course, the West has its own biases that have led to the same type of thing on our end too, such as the Piltdown Man.
