in recent years researchers have found evidence that El and Y-h were two different gods that eventually were merged into one. it is reflected both in early Israelite religious practices, originally El (El is the head of the Canaanite pantheon) alongside Ba'al and other gods was the dominant deity in the region, but eventually, due influence of Nomadic traders coming from Africa through Egypt the Israelites were introduced to Y-H.
eventually, Y-H became the dominant deity among the Israelites and became interchangeable with El, it is also reflected in the Torah and the Old Testament and Jewish practices still to this day. For example the term אל עליון "El Elyon" meaning "the most high God" was originally a title of El, as according to Canaanite mythology the head of the Canaanite pantheon and had a high house in the mountains.
