The Meru script which is the proto-Indus script known from the symbolic representations among the Harappan seals from the Southeast Asia

The Indus script, also known as the Harappan script, is a corpus of symbols transformed by the Indus Valley Civilisation, but it´s true origin is in hidden among the valleys of eastern Argentina and central Chile in South America. Most inscriptions containing these symbols are extremely short, however they are part of the meru script #Meruscript making its symbols constitute a writing system used to record the as yet unidentified language which we call the Meru language #Merulanguage. Here are some examples:

Above - The Meru script inscription approximately 30 kms NE of the center of modern Mendoza, Argentina. It is a part of the geoartscene which had been built in form of a geoglyph before 40,000 years BP.

By 1977 at least 2,906 inscribed objects with legible inscriptions had been discovered,[19] and by 1992 a total of approx. 4,000 inscribed objects had been found.[7] Indus script symbols have primarily been found on stamp seals, pottery, bronze and copper plates, tools, and weapons.[20] The majority of the textual corpus consists of seals, impressions of such seals, and graffiti markings inscribed on pottery.[21] No extant examples of the Indus script have been found on perishable organic materials like papyrus, paper, textiles, leaves, wood, or bark.[20]

Early Harappan Early examples of the symbol system are found during the Early Harappan period of the Indus civilisation, dated to possibly as early as the 35th century BCE.[22][23] Pottery inscriptions and clay impressions of inscribed Harappan seals have also been found from the Kot Diji phase of the Early Harappan period, dated to c. 2800–2600 BCE.[24]

The first publication of a seal with Harappan symbols dates to 1875 in a drawing by Alexander Cunningham.[6] By 1992 an est. 4,000 inscribed objects had been discovered,[7] some as far afield as Mesopotamia.

And one more proto-Sanskrit example from Peru which pertains to the story of Ramayana, which speaks about the lord Rama and his travel from the modern central Chile towards modern Nicaragua:
