There are good reasons to believe that Greek Mythology is an embellished version of real history. The so-called 'gods' were just ordinary men and women whose deeds have been exaggerated so that they could be made into gods. I will go into this argument in detail in my forthcoming new book, but basically they are as follows:
Oceanus and Tethys were additional children of Noah, born after the flood (and there is nothing in the Bible to suggest that this should not happen). They got married and had both sons and daughters. Their sons were called 'River Gods' and their daughters were called 'Oceanids'. One of the Oceanids, either Clymene or Asia, married Iapetus (Japheth) and they had a son called Atlas who had a daughter called Electra. She married Zeus who is the same as the Egyptian Osiris and the Biblical Mizraim. Zeus and Electra had a son called Dardanus who became the first king of Troy.
Dardanus married Batia, the grand-daughter of Scamander the River God, who represents the river near Troy. Her father was Teucer, king of the Teucrians. Dardanus and Batia had a son called Ericthoneus who succeeded him as the next king of Troy, and the line continues as far as the Trojan war. Virgil (3) tells the story of how Aeneas fled from the burning city of Troy and established his kingdom in Italy. Then there is Brutus, the great-grandson of Aeneas, who came to Britain and founded of the British (Welsh) monarchy, despite claims to the contrary which I have dealt with in Why All The Fuss About Geoffrey and The Good Book of Oxford.
Taking all this together, we have a continuous genealogy from Noah to the Welsh monarchy, but that's not all. Berosus (4), a Babylonian priest of the third century BC, gives a list of ten kings before the flood, corresponding to the ten patriarchs from Adam to Noah. So the genealogy goes all the way back to Adam.
Note: There is a more elaborate version of the descent from Noah to Dardanus, but it is based on sources that cannot be authenticated. See From Noah to Dardanus (according to Annius).
