Ogham script, the oldest known Celtic script, is a written language that would appear to be among the oldest written languages. Though, for some time, it remained far more enigmatic as it consists, simply enough, of straight and intersecting lines. Which made it one of the most basic scripts ever found.
As it only appears as a series of slashes, it remained enigmatic for some time. Yet, once it was finally decoded and realized as an actual form of ancient writing, it soon became an incredible mystery; as sites like Crack Canyon in Colorado, USA appeared to showcase Ogham script and so then seemed to be examples of ancient European contact long before Columbus.
As seen above, these sites showed an uncanny similarity with ancient Irish sites, seen below.
Beyond any doubt, an additional level of research is needed to help clarify this incredible anomaly, which isn’t simply isolated to Crack Canyon, but it is also found in ancient sites all throughout the surrounding region. Although not all show Ogham script, with some featuring Egyptian characteristics, but the prevalence of evidence which shows some form of migration from the east would seem to warrant further examination of the different site . Though this is a slightly problematic issue as the site of Crack Canyone, at the least, has been completely sealed off so that it can no longer be examined.
