This 2015 video taken at the Gault site in Texas was apparently filmed with a potato.
"At the Gault archaeological site in central Texas, archaeologists have unearthed a projectile point technology never previously seen in North America, which they date to be 16,000-20,000 years old. The findings, published in the journal Science Advances, suggest humans occupied the North American continent prior to Clovis — considered the first culture to use projectile points to hunt on the continent, and dated to around 11,000 years ago."

Note: "The Gault site, midway between Georgetown and Ft. Hood in central Texas, has a long history of archeological investigation as well as uncontrolled artifact digging," according to Texas Beyond History. "Located in a small wooded valley with a spring-fed creek and an unlimited supply of excellent flint, the site was occupied intensively during all major periods of the prehistoric era."
A large number of Clovis artifacts have been uncovered at the site and excavations of an older, pre-Clovis layer were carried out several years ago, revealing evidence of human occupation. According to Wikipedia, "[p]hysical and cultural stratigraphic evidence as well as luminescence dating are consistent in showing a coherent sequence of lithic material evidencing this older occupation followed by Clovis, Late PaleoIndian, Early Archaic, and Middle/Late Archaic occupations over an apparent span of more than 16,000 calendar years."
Considering this and other recent discoveries, I would say that the Clovis-first theory is effectively dead.
