In 1880 the German investigator Julius Wellhausen published "Prelogomena to the History of Israel". In this book he collected evidences related with the fact that the Torah, he said that Moses wouldn't have written the most important texts of the Pentateuch (the first five books of the Jewish Bible)- Wellhausen defended even the hypothesis which says that those legends talk about the Elohim or Bright Beings equivalent to the Annunakis, proceed from oldest fonts, those fonts, latter, will be identified with Sumerians. After Wellhausen, the advances on the textual and religious critic had convinced many experts and historians on the fact of that those texts, as we know them now, were taken and adapted from different fonts. Now we know that the font is Sumeria.
In order to cast light on, the term Elohim is an hebrew word used by Jewish and the priests, they use this word to name God, but Elohim would be His plural: gods. In the original Bible, the hebrew, they don't talk about an only god but about gods... the Elohim. Time later this word started to be used in singular "god" when the monotheisict religion was unified, so, the religion which worship an only god.
Now we know that Enuma Elish is a summary of legends with a sumerian origin, like it would happend with Babylonian beliefs, it seems to be a history about the birth of our Solar System. The Enuma Elish was written in seven tablets and biblical Genesis took place on seven days. God rested on the seventh day of the Genesis and the seventh tablet of the Enuma Elish is an appreciation of the work of their God. It narrates the construction of Babilum ("Archade of the gods" Babylon) and a ziggurat dedicated to Marduk, but supposedly it was dedicated to Enlil; in the Bible they talk to us about the "Tower of Babel". The samples are countless. The chaos, abyss over the water or "Tehom", it was named Ti-amat in the Enuma Elish, and was the monster which represented the chaos.
The most part of biblical stories and characters are based on stories with sumerian origin. On this way, the ten first biblical patriarchs are the same than the sumerian antediluvian kings. Between the ten antediluvian kings we can find Alulim, that was "who spread the seed" (Adam), his son Alalgar (Set), and others like the shepherd Dumizid who was murdered (Abel), Enmenduranna (who knew the secrets of the skies, Enoch), Enmengalanna (who knew how to get the mediation of the gods, like Enós and his praying), the mentioned Ziusudra (Noah) and his father Ubar-Tutu (Lámek). In Sumer were the gods which decided the destruction of the man because of his meanness, like in the Genesis, but only one of them (Enki) had pitty of the humankind and he ordered to one man the construction of a ship and fill it with animals.
The Universal Deluge is the name of a sumerian legend and, latter, the name with which we know an event narrated in the Genesis, first book of the Bible, about the story of Noah and the punishment sent by God. If texts like those of the Bible are copies of ancient sumerian texts, we can say that they were inherited from the Babilonic period, so they are pagan beliefs supported by the politheism.
There is a Sumerian text that is usualy named the Poem of Gilgamesh, is a narration from Mesopotamia with Sumerian origin considered as the oldest narration of the History. They used tablets of clay and cuneiform script, this favoured its preservation. According with the Royal Sumerian list, Gilgamesh was the fifth king of Uruk. The poem tells the adventures of the king Gilgames, also known as Istubar and his friend Enkidu in their search of the inmortality. One of the tablets talk about a chapter very similar to that in the Bible about the deluge. It also mentions another serie of details very similar to those that we can find in the Bible, like the Cherubins which protected the access to the "tree of the life".
