After many years of research I’ve concluded that jesus was a new god and then was exalted to high god absorbing the powers and likeness of his father. Many years later the trinity idea was introduced to Christianity. This was not uncommon for many pantheons of gods had this happen.
In Babylon Marduk defeats Tiamat and for this he is given highest god status even absorbing 50 other gods and thier powers.
Baal basically does the same by taking over for El not replacing him but becomes more revered because of his fertility powers.
Osiris does something similar and Horus is given the powers and takes over for RA after his mother tricks RA into telling her his devine name.
