Improbable as it seems the Greek alphabet was supposed to have been devised by a Phoenician and a Druid and then exported to Greece. On the face of it, this seems impossible as the generally accepted date of the founding of the Druids is about 1500 BC (before Prince Brutus arrived) but this might be a modern convention. However, according to William Stukeley early Britain had been a Phoenician colony, the finest surviving monument to this period is Stonehenge circa 2500 BC. It may come as a surprise but the Druids were great scholars and although they were forbidden to write any of their doctrines down, they had to memorise them, yet for business and other matters, they did write things down - using Greek.
