IIRC yahwism came from the canaanite polytheism and while that god is very similar to zeus it is actually a different and unrelated tradition. Similarly certain numbers and especially the flood theme recur across mythologies that are proven to be unconnected. You can't take even very clear similarities and use them alone to draw connections between traditions like that. In fact the allure and inevitable failure of this approach was at one point enough of a cliche that the reader's awareness of it is assumed for a major plot point in the novel middlemarch, written 150 years ago.
