The Enigma of Pelasgians and Etruscans the relation to Indus Valley civilization

 I am interested ancient civilizations and their language and writing systems.
I'm specially intrigued by the Indus Valley civilization and the Indus Valley civilization's writing.
While I was reading about this I came across this article which seems to be quite related to the kind of writing which is at to be deciphered from Indus Valley  civilization

The Enigma of Pelasgians and Etruscans "Pelasgians, ancient people, the ancestors of all the Indo-European people, these people were known to illuminate and give the culture to Europe, about them it is known little, or better to say nearly nothing. The' alphabet of these mysterious people is called Pelasgic from the civilization that created it, DIODORUS SICULUS informs to us that the Pre-Homeric poets expressed themselves just with that alphabet, and from the same source, we learn that, at least 10 centuries aC. That same writing was used. Moreover Diodorus reports that they were the first to bring their alphabet in Italy, as well as to the rest of Europe, practicing opportune adaptations and improvements. Also Pliny the Elder confirms the information of Diodorus. Virgil (Aeneid, VIII, V. 62-63), writes: "It is said that the first dwellers of our Italy were the Pelasgians" . From the ancient authors we have learned that before the arrival of the Greeks, those territories were known as Pelasgia, the several sources inform to us moreover, than the Greeks learned from the Pelasgians not only the art of the working of the metals, of the construction of walls, but they learned, improving it, their way of writing and made their divinity their own."

"Herodotus has explained to us that, before the arrival of the Greeks, that territory was called PELASGIA. He also told to us that the Greeks learned from the Pelasgians the art of the working of the metals, the construction of walls, the writing that refined and that until the discovery of the Latin, was the only divulgative (the act or an instance of divulging or spreading abroad : publication, disclosure)writing. Still today, in the several museums of Albania there are epigraphs written up with the Greek alphabet, whose content it is comprised however not with the Greek language, but with Albanian, with the exceptions of a few neologism."
