Not only that, there's evidence to suggest he was just an amalgamation of various sky and storm gods rolled into one. Shit, even the entire concept of angels and demons (or Aevas and Daevas) wasn't added to Judaism until the Persian empire invaded the region.
And Jesus didn't even exist. Literally every single one of his so-called "miracles" were claimed by various prophets whose stories were up to centuries older than when Jesus supposedly walked the earth.
Fuck me, the Jews were never even enslaved by the Egyptians. The time period when they supposedly were enslaved was when Egypt had entered a period of open trade with the rest of the region. This information is corroborated by Mycenaean artifacts.
Demon also used to mean more along the lines of a neutral spirit that inhabited nature and/or things made by men. Christians are fucking stupid.
