When I said the Essenes apparently invented baptism, I was referring to a group of Jews who split from the Temple and went into the desert to get away from the infighting between the more dominant sects like the Pharisees and Sadducees. So yes, baptism was probably invented by Jewish Essenes, and the Christians incorporated it into their religion without acknowledging where it came from, which may be due to dishonesty, secrecy and fear, or possibly they simply lost their own history.
The Essenes are important because they left us the Dead Sea Scrolls. The Dead Sea Scrolls are important because they are the oldest Bible artifacts - and because they contain other writings that did not survive.
Below is a Roman denarius minted in 18 BC. On the left it says "Augustus" and on the flip side "Son of God".
Why the Jews wanted to create a Son of God named Jesus, to clash with the authority of the Romans, makes no sense. Besides, we know the 69 AD Roman War in Judaea was a Hebrew rebellion against the erection of a Roman statue inside the Temple, to try to force the Jews to worship Roman rulers. Whatever happened to cause the story of Jesus to arise from this disaster is hard to say. Probably Jesus is a symbol of the Zealots who were freedom fighters who the Romans probably considered terrorists. (The Romans stationed in Judaea, and their superiors back in Rome who learned about the Jewish uprising through messages.)
You mean we are all children of our parents. And the parents of the human race were protohumans, which is why there are so many apelike human skeletons from millions of years ago.
Besides God can't have children since he doesn't have a uterus, and if he did we'd all be asking who our father is. If you said "God the Father" that complicates matters a bit since we don't know which one is the real father, El (Ilah, Elohim, Eloah, Allah) or Yahweh.
Early Semites believed that Yahweh took a wife, a goddess named Asherah, and she was their goddess of fertility, but it's unclear if they believed she was the mother of all humans. However that would be the logical conclusion following a belief that she was the wife of God who created humans.
Archaeologists have found thousands of statuettes of her from ancient homes in Isreal. Wave, and say Hi Mom! :wave:
She was a busy lady up in Ugarit where she had seventy sons. Phoenician sailors may have brought her to Ugarit from Egypt. The Canaanites had contact with them, so it's easy to see how they may have brought Asherah to their villages with the story that she was married to Elohim. In any case, Jewish religion is tied to Ugaritic and Egyptian religion on this subject.
