Isn't it possible the the foundations of the Hebrew tradition came from Sumerian myth?

I've been doing some research the past few days (that's why I haven't been here) on Sumerian myth and religious tradition. I couldn't help but notice that there are strong comparisons between Sumerian mythology and hebrew mythology. In Sumerian legend, the Annunaki are strangely similar to the Nephilim in the Apocrypha and the Talmud. Also, Lamastu a Lilith figure with uncanny similarity. Since the book of genesis says that Abraham came from the Babylonian city of Ur, and since Babylon was in the same geographical area as Sumeria, isn't it possible that when he established his tradition, he lifted it from ones he was already familiar with? Could it be that Judaism, Christianity, and Islam are all descendants of Sumerian religion?
