What's the level of mutual intelligibility/transferrenc between ancient/modern Greek?

[Geticus]

Aboriginal refers to indigenous. How can a Latin inhabitant be aboriginal if he or she is Greek? Do you mean to say that the Latins were originally Greek colonists? Just to be clear, you are referring to people of Latium, not Etruscans or any other peoples of the Italian peninsula, correct?

Regarding previous comment, I don't need to speak for every single linguist that ever lived. It's just the common consensus. Like some mentioned before me, Latin and Greek are shown to be part of the same language family but different enough to justify their being classified as separate languages and not a case in which Latin developed from Greek or where Latin was a dialect of Greek.

Again wrong, the word aborigines is a Latin word specifically referring to the ancient Latin stock. Generalization of the use of that word to signify any nation or ethnos that was thought to have inhabited the land in early times was a later transvaluation of the word. Its etymology in ancient times was disputed but I accept the viewpoint put forth by Dionysios deriving it from Hellenic ab (from) + oros/genetive origos (hill) signifying the well know ancient historical fact that after the deluge the prisci Latini had lived in the hilly and mountainous regions of the Apennines, including the earlier seat of Latin royal power at Alba Longa prior to the rise of Roma and the shift towards the Tiber river and the coastlands and plains of Latium. In later times the word ABORIGINES was used to describe any person or nation of ancient origin. Do you not know that the Roman historians generally refer to the proto-Latin stock as the aborigines? The word was used specifically for the proto-Latins. Many Latin words have been transvalued in more recent times, especially after the rise of Christianity. For example, I don't believe any ancient Roman historian ever referred to any of the other early Italian nations as aborigines. This includes the Sicelii, the Italii, Samnites, Etrusci/Rasenna/Tyrsenoi etc. Only the Latin people were designated as aborigines because it was their general ethnonym before the word Latini became dominant during the late bronze.
