Not so...
"The Ugaritic texts offer innumerable literary and religious parallels to biblical literature. The parallels are so rich and in some cases so specific that it is evident that the Ugaritic texts do not merely provide parallels, but belong to a shared or overlapping cultural matrix with the Hebrew Bible. Ugaritic literature may not predate the earliest biblical sources by much more than a few decades, but the bulk of biblical literature dates to centuries later. Moreover, unlike the coastal, cosmopolitan center of Ugarit, ancient Israel’s heartland lay in the rural inland hill-country considerably to the south in what is today Israel and occupied Palestinian territory. Despite these important differences, Ugaritic and biblical literature are not to be understood as representing entirely different cultures, but overlapping ones."-
Ugaritic and Biblical Literature
So, they are overlapping with "Jews" in which I take the "Jews" as members of the Tribe of Judah. Others say "Jews" means from Abraham and on down to Judah including the other 11 Tribes of Israel. Ugaritic text and Hebrew are very much alike. 800 years would have made the two completely different much like Old English and New English.
