Hi Dennis,
apart from the fact that it seems you didn't read Pjotrs answer where he
explained why Greeks - living in a culture with many different religious
systems - tended to apply their god's names to all other religions of their
times (not only the Egyptian), you haven't explained yet why there are
hardly any material imports to Greece from Egypt that ought to have
accompanied religious 'imports' !
Also you write:
>There is a limestone plaque from Mycenae showing the arms and legs of a
goddess coming out from behind a figure 8 shield, This image has been seen
as an early representation of the Palladion, the standing suit of armour
associated with Pallas Athene.
Of course, this may all be coincidence<
No, it certainly wasn't because the image of the figure 8 shield was a
popular import from Minoan Crete (at least since Late Minoan times). So
either Athene came from here (e.g. under the name of a-ta-na-po-ti-ni-ja,
although that is still in doubt with Mycenologists because there are other
potniae, too) or you are just wrong ...
Best wishes
