The Topper radiocarbon date shows a classic symptoms
of "fringe" science: results that at the edge of resolution
or near the noise floor of any particular measurement method.
He's close to the edge of the ability of radiocarbon dating
(about 60K years), and the anthropogenic origin of his stone
tools is in question.
Time will tell, though. Plate techtonics was hinted at in
the 16th century, and again in 1912, but took another fifty
years after that to become widely accepted.
Always listen to experts.
They'll tell you what can't be done, and why.
Then do it.

In part because the mechanism was missing from the theory. I find it interesting that even objects suspected of being made by humans require multiple lines of reasoning and evidence to distinguish them from natural formations.
