Can you tell us in more detail why some studies suggest that children were sacrificed in Carthage? This ritual was supposedly called Moloch, and is sufficiently described in ancient sources.
I cannot give you any sort of in-depth deconstruction of what you have presented, but the reality is that it doesn't matter. Whether these stories are manufactured lies by the enemy, or whether done by misguided Gentiles, it doesn't change the fact that the Gods do not support it, nor does any real Zevism, because it is highly unethical and disgusting, and also inefficient for any actual creation/empowerment within or of a civilized society.
