Alien script? Ancient basalt tablet found in Georgia where 60 characters belong to no known language!

Were there more civilizations on the Earth that never got discovered? Imagine uncovering a forgotten language from a civilisation inscribed on stone, left behind by an ancient civilization that got lost forever in the annals of history!
This is exactly what happened in the Bashplemi Lake region of Georgia, where archaeologists recently discovered an ancient piece of art. This region is already rich in historical significance because many ancient human remains have been found there, and now this discovery has made it endowed with an even deeper mystery.
A basalt tablet, measuring 9.4 x 7.9 inches has been found that contains seven rows of detailed writing etched on the piece. Researchers believe the script could be connected to early Georgian or Proto-Kartvelian languages, but there are also similarities to Semitic, Brahmani, and North Iberian scripts. Despite these similarities, the characters appear to be from a previously undocumented language.
The tablet's finishing suggests it was created by a skilled artisan using advanced tools, including a conic drill for the initial holes and a smooth, round tool to connect these into flowing lines, these details also tell us about a high level of precision and artistry. The purpose of the writing still remains a subject of mystery. However various theories predict the documents for recording spoils of war and building works, and possibly, solemn gifts given to the gods.
The team of archaeologists from Georgia has confirmed that the inscriptions represent a script never recorded before. This brings in questions about the distribution and preservation of the writing all over the transcontinental region. This tablet is about the size of an iPad, which has 39 different characters and 60 inscriptions all left to right across seven lines. Each of these symbols were created as holes made using a cone-shaped drill and then connected into smooth lines by advanced tools.
After analysing the basaltic piece using optical and electronic microscopy along with an examination of the surrounding area, researchers have suggested that the tablet's origins date back to the region's Bronze Age. The dating of basalt hints that the tablet was created from local materials.

Althought the artifacts like this basaltic rock are a new discovery to the researchers, the symbols appear similar enough to Middle Eastern scripts and undeciphered symbols of pre-Christian Georgia to make any conclusions by non-scholars improbable. "We believe that at this stage there is no reason to doubt the authenticity of the artifact," the team wrote in a published report.
The early records of the region are ancient in the sense that they carry a date as early as the 6th century A.D. at the onset of the spread of Christianity. However, archaeological evidence states that settlements and metallurgical activities are thousands of years old. The Dmanisi region consisting of the modern territory of Georgia was a melting pot of cultures leading to various inscriptions "from that time".
Epigraphs have been discovered from the ancient capital of Mtskheta-in Greek, Hebrew, Aramaic, and Middle Persian-which is situated about twelve miles north of present-day Tbilisi, the capital city of Georgia.
Segments of undeciphered images and seals from various sites in Georgia indicate the development of scripts that are still to be decoded.
Great Greek and Roman writers mentioned an early writing form that was said to belong to Colchians, the people who inhabited areas east of the Black Sea. Nothing has survived from their writings, but some believe that the inscriptions found on ancient pottery may indeed be traces of Colchis' writing.
This region bridges Europe and Asia, so discovering yet another strange script is not surprising. The shapes of the letters resemble Middle Eastern symbols and is similar to the seals from Bronze and Early Iron Age Georgia. Researchers also note the signs' resemblance to Proto-Kartvelian scripts, a precursor to modern regional languages.
