Here is another good article that stops the bias in this forum.
Polytheism and Ancient Israels Canaanite Heritage. Part V
Of course, much of this [i.e., that Israel worshiped El and Asherah alongside YHWH] is really to be expected given that recent syntheses of the archaeological, cultural, and literary data pertaining to the emergence of the nation of Israel in the Levant show that most of the people who would eventually compose this group were originally Canaanite. As the Hebrew Bible notes, the Hebrew language itself is a Canaanite language, literally the lip of Canaan (שְׂפַת כְּנַעַן; Is. 19:18), and so it cannot often be distinguished by modern scholars from other Canaanite inscriptions on purely linguistic grounds.
[1] Moreover, during the Late Bronze and Early Iron I periods both linear and cuneiform alphabetic scripts are attested in inscriptions in the highlands as well as in the valleys and on the coast.
[2] Furthermore, specific technical religious terminology for cult sacrifices and personnel in Israelite religion often have exact correspondents in Ugaritic and Phoenician.
[3] Further, Israelite material culture is extremely difficult, if not impossible, to distinguish from Canaanite material culture in the Late Bronze and early Iron I periods.
[4] Rather, it shows direct continuity with the preceding ages and cultures in such features as collar-rim jars, four-room house architecture, cisterns, and burial patterns.
[5] Archeologists have tried to provide a clear set of criteria in order to distinguish between Israelite and Canaanite sites in the earliest periods, but often with little success (though not for lack of trying). Additionally, the texts of the Hebrew Bible, although admittedly written hundreds of years after the events they purport to record, complicate matters by further noting the existence of many other foreign groups in the land (e.g., Ex. 6:15; Josh. 3:10; 9:15; 14:13-14; Judges. 1:16; 1 Sam. 27:10).
