sure, if you like human sacrifice, slavery, mass murder, idol worship, ignorance, steeped in darkness, etc, go live there
Yes, because human sacrifice, slavery, and mass murder have NEVER occurred in Christian civilizations. Well, other than in European/US civilization over the last 1000 years or so, that is. I'd bet there's been some idol worship in our civilization, too, and I know that there's been quite a bit of ignorance and darkness in our civilization. Judge not, lest ye be judged. None of this is pertinent, however. Your original statement was that there cannot be civilizations without Christianity. I gave several counterexamples to that statement. It is irrelevant whether or not you approve of those civilizations; they are nonetheless civilizations that arose without the benefit of Christianity.
