I find it hilarious when people insult Yahweh. For one thing, man did not invent God. God invented man.
I know what you mean, too. The Greeks, Egyptians, Indians, Mesopotamian, and so on. Their gods are indeed laughable.
Defend 1 of those claims about Yahweh. 1. Much less all 3. You can't just walk in and insult people or their religion without a decent reason or explanation (obviously you can on the internet - but you can't as a reasonable human being).
