You may have misread the Smithsonian article that says "Spanning the past 2.6 million years, many thousands of archaeological sites have been excavated, studied, and dated" to conclude that stone tools date back 2.6 million years. Some of the sites may be that old but the tools cannot. Humans only evolved in the last half million years.

Fair point, I should have said hominids in there somewhere. Although saying "humans and hominids" all the way through would have been a little inelegant.
