God had to impregnate a teenage virgin with himself, so he could become his own son, grow up and then sacrifice himself to himself to save us from himself?
Christian cosmology: A talking snake in a magic garden convinces a gullible woman to eat an enchanted (but forbidden) fruit which makes the invisible sky god very angry. The sin this woman committed? Partaking of the Tree of KNOWLEDGE. Daring to want KNOWLEDGE, the enemy of religious superstition and the one thing that can destroy its power to control the ignorant.
So this petulant, admittedly (self-described) “jealous” god curses Adam and Eve with an evil spell called “sin” that, after drowning women, children, babies, old people because they had too much of this curse, he decided it could only be cured with a human sacrifice, in which god has to impregnate a teenage virgin with himself, so he could become his own son, grow up and then sacrifice himself to himself to save the world from himself, but only for those who demonstrate their acceptance of the sacrifice by eating his flesh and drinking his blood and wearing a miniature implement of death penalty around their necks.
