King Darius prayed to Ahura Mazda for success in his battles with Alexander the Great, who prayed to the Greek gods to grant him victory. History showed us whose gods were stronger.

Interesting.

Alexander claimed to be the son of Zeus Ammon, the Greek version of the Egyptian oracle god, Amun. Amun had the horns and legs of a ram; and in the Zoroastrian tradition, was considered to be one of the evil spirits, the eternal rival of the Persian god Ahura Mazda. Ever since, the devil is depicted with ram's legs and horns.

Ammon is probably related to Baal Hammon, or what we now call the Semitic god Baal.
If you want to believe Alexander's defeat of Darius III depended on Baal being "stronger" than Ahura Mazda ... that's your opinion.

I'll put my money on the capture of Tyre and 60,000 Macedonian reinforcements. JMO.

For the record, I don't believe "the gods" helped Alexander win his battles. I threw in that comment for levity's sake.

Alexander's leadership, his cadre of competent officers, and the esprit de corps he instilled in his soldiers, were the deciding factors.
