I think the resemblance of
Ask and Embla to Adam and Eve is so close as to suggest a copy, but the story of Adam and Eve is undoubtedly far more ancient as Moses was circa 1500BC.
As for the Greek Garden of Hesperides and the Golden Apples, the garden was allegedly situated in the Atlas Mountains in West Africa or in Portugal, and Adam and Eve became Zeus and Hera.
Well, in some myths, that is.
"The ancient mythological record is not unanimous as to the location of the wedding of Zeus and Hera; “several places in Greece claimed the honour of having been the scene of the marriage, such as Euboea (Steph. Byz. s. v. Karustos), Samos (Lactant. de Fals. Relig. i. 17), Cnossus in Crete (Diod. v. 72), and Mount Thornax, in the south of Argolis. (Schol. ad Theocrit. xv. 64; Paus. ii. 17. § 4, 36. § 2.)” (from William Smith’s “Dictionary of Greek and Roman Biography and Mythology”)." See

However in the account of the children of Zeus and Hera that there are parallels with Cain and Abel and Seth, but ultimately huge divergence.
"The Greeks deified Kain as Hephaistos, god of the forge. They deified his younger brother, Seth, as Ares, the troublesome god of conflict and war. In the Judeo-Christian tradition, Kain is the evil one whose way is to be shunned. In the Greek religious system, Ares, the Seth of Genesis, is the traitor and the one who causes ruin and woe."
"While the scriptural viewpoint defines Seth/Ares as the God-believing, or spiritual son, Greek religion defines him as hated by, and antagonistic to, the ruling gods who are part of the serpent’s system. Likewise, while Zeus-religion looks on Hephaistos/Kain as the true and devoted son, the scriptural viewpoint defines him as part of the wicked one’s system. Jews and Christians dislike and shun the line of Kain, but they can’t get rid of him or his line without altering their spiritual standpoint and history itself. Kain is part of the Scriptures, and he is there to stay. Zeus-religion has the same kind of situation. It hates the line of Ares, but it cannot eliminate the line from its history because the basic achievement of Zeus-religion, its grand celebration even, is the triumph of the way of Kain over the way of Seth. Ares is part of Greek sacred literature and art, and he is there to stay."
The Greeks lionize Cain, whilst the bible lionizes Seth. Obviously the Greeks chose the wrong champion, the way of error. May be there is a point to this. It's new to me.
What can one say? I think the pagan stories only make any sense when one knows the biblical story. I should think that they share a common source, but I'd doubt the Greek one was earlier than the biblical one. Moses was circa 1500BC and
Greek mythology was much later circa 1000-700BC.
