Alexander the Great:

Prophesied by oracles (and in the Book of Daniel)

Born of a god (Zeus-Ammon)

Received divine omens

Worshipped during his lifetime

Conquered the world

And believed by Jews themselves to fulfill prophecy.

If miracles disqualify history, throw out all ancient sources.

If you tolerate miracles as literary color, then Jesus gets the same treatment.

Apologists demand faith for Jesus, but dismiss miracles in others.

Academics dismiss faith for Jesus, but accept miracle-filled Alexander.

If you adopt the perspective that both figures are part of a unified literary universe, then you can either step into that world and realize both are divine figures, or you can step out of it and realize it's all fiction.

Otherwise it is like a faithful believer arguing that Hulk isn't a real superhero but Spider-man is, or a "Marvel Historian" arguing that Captain America was real but didn't have super powers and spider-man is a constructed myth. Both are completely trapped inside the literary matrix desperately trying to make sense of it.
