I need clarification on this. Some say it is Enochian, but I don't think that is the true native language. I also heard was Zapoqra, which was similar to Sanskrit, but not quite. Need help clarifying this. Thanks.

No BS answers like Hebrew or Arabic. That didn't start until after the Egyptian years.

Hebrew and Arabic started before the Egyptian years, but that has nothing to do with angels. Who do you know or have heard of who know what language they speak? Why does it matter?

Angels and demons would probably speak in the same language whoever they were addressing.

First of course, a very large section of the population do not even believe in Angels or Demons. In China they would believe their gods speak Chinese. As so some other locations.

There is no actual record. Basically it is unknown, which means man would not know it, or be aware of it. They can of course speak any language on earth, since for those that believe, they have appeared and speak many earthly languages.

And of course the issue, if the oldest language is just oral, not written, it could be lost with no record what so ever.

There is no agreement as to what language, in China, they claim that all civilization comes from the Yellow River area and the oldest language is a old Chinese one.
