Why some people believe that vikings traveled in Oklahoma?

Some people believe that Vikings traveled to Oklahoma due to reports of Norse artifacts and structures found in the region, such as the "Heavener Runestone," which features inscriptions resembling Old Norse. Additionally, the idea is fueled by theories suggesting that Vikings explored North America beyond the well-documented areas like Newfoundland. These claims, however, are often met with skepticism from historians and archaeologists, who argue that evidence is insufficient to confirm Viking presence in Oklahoma.
