Traces of the Ancient Greek language

Did the Hellenes traveled to the Pacific Ocean?

If the Hellenes did not travel to the extremities of the world, then what explains the following scandalous lexical similarities?

Greek alphabet was in use at 6000 BC.

The potsherd of 5500-6000 BC, found at the islet Yura of Northern Sporades bearing Greek alphabet letters. The facsimile to the classic Greek letters Alpha, Ypsilon and Delta can be recognized. This find proves that the classic Greek alphabet is older than the Greek linear alphabets. It also demolishes crushingly and definitely the false theory that Greeks took the alphabet from the Phoenicians, who emerged in history around 1150 BC, i.e. 4500-5000 years after the creation of the Yura written potsherd.

After the discovery of a wooden plate at Dispilion Kastorias, which was dated at 5300 BC, a new impressive discovery came to light, concerning the "prehistorical" alphabet in the Greek region. In the "Cyclop cave" at the desert islet Yura of Northern Sporades (20 miles out of Alonissos), ceramic fragments of written pots (potsherds) were excavated, upon the surface of which have been carved symbols facsimile with the letters of the classic Greek alphabet. The potsherds are dated between 6000 and 5500 BC.
