Many historians or documentaries, when they touch the subject of the Bronze Age collapse they always talk about the Sea People and their contribution to the almost apocalyptic event. But their identity, to my knowledge remains unknown.

Now the Mycenaeans had a strong naval presence, establishing various trade routes that reached as far as England. Their civilization ended somewhere around 1100 BC, the end sealed with the Dorian Invasion or Migration. There are many theories suggesting that Mycenaean Greek collapse had something to do with a civil war. So it was a "Self-destruction". Greeks have a long tradition of schism and wars between them ( Greek Civil War of 1823-25 fought during the Greek revolution, The National Schism between Venizelos and Constantine I 1911-1922 when on one point in 1915-1917 Greece was split in half, The Greek Civil War of 1946-1949) and all of them only in the 20th century. Previous well known conflicts like the Three Peloponnesian Wars and the Byzantine Iconoclasm. So really civil war is in my country's genes.

Now sorry for the wall text but this is my question. Since there's a theory about Mycenaean Greece destroying itself on a rival conflict, is there any chance the Sea People had Greek origins and were possibly Mycenaeans? Which could also explain the Trojan War. Since Troy VIIa appears to have been destroyed by a war and there are traces of fire. Mycenaeans forced to migrate or invade other nations like Egypt and the Hittites, or even becoming pirates.
