Yahweh

Most scholars believe that the Tetragrammaton should be pronounced "Yahweh".

I will execute great vengeance on them with wrathful rebukes; and they shall know that I am Yahweh, when I shall lay my vengeance on them.

Contrast this with, say, Zeus in Greek mythology—powerful, but flawed and contingent—or the Judeo-Christian God, who’s absolute and uncreated. Extraterrestrials might land closer to Zeus than Yahweh: impressive, but not the bedrock of existence. Still, if they seeded life on Earth (a panspermia twist), some might argue they’re "creator gods" in a limited sense—though that’s more like being master gardeners than omnipotent deities.
