—“Claim: Zoroaster and hence Zoroastrianism was the ultimate impetus behind both Greek Philosophy and Christianity.”–
That’s not true, but it certainly had influence by the first century AD on Christianity as Persians sought dominance over their empire and as other religions sought monotheism as an opposition to indo european dominance of old river valleey civlizations.
Greek philosophy evolved from greek law. Only late was it influnced by other religions as the world sought a solution to ethics as trade expanded, travel expanded, and contact increased, and empirs sought solutions to rule, and people sought solace in religion as their alienation increased – just as it has today.
