Because there’s nothing moral about Yahweh, that’s why. And, all of the things he said was directed to the Jews only.

Ancient Egypt has an older morality. I think the ancient Greeks are much more responsible for western morality, alongside the ancient Romans. the ancient Chinese have a morality which predates the Bible etc.

Of course, it should be abundantly clear to everyone that the Bible is not the least bit moral in nature. Nor is it spiritual. A book that instructs genocide, infanticide, child abuse, child sacrifice, animal sacrifice et al is not the source of anyone’s morality.
