Marduk = Abraham. 

The early prophet line is reflected in all the history of the world.

Marduk is a regional variant of Abraham. So is Zoroaster.

Adam as we know him, was the first prophet of Dyeus, and the first human consciousness we see in history. Dyeus, became Zeus, Jupiter (with piter from fertilitycult distortions) and Yah, etc. "God" ofcourse for many.
Idris was the second prophet of Tengri, which became "Thor" many places sometimes god, sometimes more of a prophet, and again "Indra", "Prometheus", "Osiris".
These concepts are known everywhere with local variations.
Knowing the regional names, one can see the same change in the regions who talk about Marduk, as here. A change from early prophetic teachings, to that of Abraham.

And Sarai of the Bible, is Saraswati in Hinduism, and Sarpanit here. Obviously we all have the same prophetic line, teaching monotheism. - God is without others.

Peace Be With You.
