Lack of evidence is not evidence. Just because there is no "smoking gun", which is very hard to produce after 10,000 years, doesn't mean that the theory is discredited. It just means that the criteria that these authors set for evidence was not met.

They found that Clovis people hunted mastodons, and mastodons went extinct shortly after. See, that is proof of climate change causing the extinction. Their logic, that they did not find enough evidence of predation is poor, because how do they define what "enough" evidence is?

"Lack of evidence is not evidence. "

The maker of the theory must prove the theory. It is not up to others to disprove. IMO, the theory has not been proven.
