just because Lao Tzu didn’t really write the Tao Te Ching that doesn’t mean a thing

It’s a bit different — Lao Tzu (or “Old Master”) did write the Tao Te Ching, we just have no clue who that person was (Tao The Ching is not pseudepigrapha).

Pentateuch

You have left out that Semites were present in Canaan well before “Moses’ return” (there is also no archeological evidence for Exodus on the scale described in Torah). The second thing you have omitted — according to the Hebrew lore, their original religion came from Mesopotamia, specifically Ur (Abraham). I suggest, you look up proto-indo-europeans and their migration from Pontic steppe (started 4000BC) — you will then understand why Jewish God refers to himself “I AM that I AM”, exactly as Vedic tradition refers to Absolute as “I am Brahman”. All in all, what you see in Torah is a mixture of the original non-dualism from Pontic steppe mixed with local traditions (kind of perversion of the original idea, hence emergence of god-kings as seen e.g. in Zoroastrianism). And just as a side note — what Abraham allegedly brought from Ur was not Zoroastrianism, but that original Pontic philosophy.
