Anyone ever wonder just WHO was on planet Earth to kill Cain then? Why was he worried about being killed as he roamed the earth - a total vagabond? There was no one else around - right. . . . but Adam and Eve. Was he afraid his own parents would kill him?
Adam and Eve had by this time had many children and perhaps theyhad had children also. , this is where Cain’s wife came from and the pop[ulation for his city.
Adam and Eve were not the first or probably the last human creation. The bible also refers to Gods in plurality. Genesis is one of the most vague chapters in the bible.
