Moloch is the god of child sacrifice.

I assume you have a decent source for this, and are not just taking the bible (which advocates the destruction of moloch worshippers down to the last child) or Roman sources (who regarded Carthage as their greatest enemy) at face value, given that this sort of thing is an extremely common form of atrocity propaganda in all eras we have knowledge of including up to the present day. Otherwise, well, I'm sure you can find remains that support the claims of conquistadors that Aztecs sold human flesh in their markets or American claims of millions of dead Uyghurs. To my knowledge we don't even have particularly good proof that there even was a god called "moloch", a quick browse says that many modern scholars think the word may have referred to the sacrifice itself, and not a figure of worship.
