since flies cannot be lord of anything, the title "Lord of the Flies" is meaningless
to be more clear
Beelzebub literally means Lord Of The Fly but in this case, the singular should be interpreted with an English plural (for instance: the phrase "king of the Amalekites" would in Hebrew be written as "king of the Amalekite").
Beelzebub means Lord Of The Flies but since flies accept no central rule, it's an empty or even mock title.
call bullshit all you want but the Egyptians and pagans were here long before Jesus and your Christianity.
Maybe you should actually read the history of the making of Christianity before shooting off your mouth
