This may blow your mind, but what if the "People From the Sea" are Odysseus, his family, and his crew?

* It was Penelope herself who voiced her fear of the People From the Sea. Did anyone outside of this group mention the People From the Sea? Was anyone outside of the group anticipating, terrified, or already terrorized by some other group?

* Ithaca is an island kingdom; anyone who lives there is a sailor by experience, and all of Greece is a region of islands and archipelagos

* Odysseus and his crew had not seen them or found them, because they are not sufficiently self-aware or spiritual

* They violated the Law of Zeus. All of them.

* That's why the Trojan Horse didn't have wheels. It was terrible to drag across dry land, but it was made of buoyant wood. It was a seahorse.

* Everyone they met, from the Trojans to Circe to Calypso and the Cyclopes, obesrved them to approach from the sea, land on the shore, and leave the same way

* They (Odysseus and his family) ultimately attacked Ithaca (the suitors)

* Odysseus, his wife and son go into exile by boat, and sail west, [beyond Gibraltar], thus permanently becoming People Of The Sea

* The Odyssey is a myth, fiction, legendary, and none of its characters actually existed

* The People From the Sea are not mentioned in Homer's text. They're extra-canonical. They were hypothesized, starting in the 19th century.
