Honestly a lot of the gods throughout history are just copy paste revisions of Nimrod, simiramas and tamuz. They are likely copy pastes as well but it seems a lot of the lines seem to coalesce there.

Like baal is either nimrod or Tamuz, so is chemosh, moloch, Marduk and so on. I'm sure moloch was an actually "god" it was just heavily associated with sacrifice.

It still exists. It's name is just changed from moloch to "my body my choice"
