1 Elohim is the name of the creator in Genesis. Elohim is a semitic plural and should be translated "the gods". 2 YHWH didn't say: "I'm the only god". He said: "I'm a jealous god and I don't want you to worship any others". 3 There is a theory that YHWH ("He is who is") was really Seth. This Egyptian god was expelled after killing his brother Osiris (who later resurrected). He swore that he would take revenge by becoming the mightiest of all gods. He succeeded: currently about half the world population is worshipping him. First he tried it with Akhenaten, when that failed, he used the enslaved Hebrews to spread his cult. Later, he sent Jesus and Mohammed to convert the rest of the world.
