There's an old saying about online headlines: If the headline asks a question, the answer is always no. If the answer were yes, the headline would say so.
Only if we count 35 years of archeology at Gobekli Tepe as 'unknown'.
I find this particular set of archeological investigations to be amazing, and I'm glad to see larger awareness of them. But I think there's a good argument that Betteridge's law of headlines still applies.

It is based on the assumption that if the publishers were confident that the answer was yes, they would have presented it as an assertion; by presenting it as a question, they are not accountable for whether it is correct or not.
A 2016 study of a sample of academic journals that set out to test Betteridge's law and Hinchliffe's rule (see below) found that few titles were posed as questions and of those, few were yes/no questions and they were more often answered "yes" in the body of the article rather than "no".[12]
