Hooberus...Ancient Near Eastern Texts edited by James Pritchard is a defintive source for this material. It has been printed in condensed form , meaning less documents not abrieviated translation, in paper back volumes. For a quite reasonable cost you can have a word for word translation of many of these Summerian, Ugarit, Babylonian, etc writings. Newer materials found or translated in the last 40 years may be available only through trade sources, scholarly periodicals and journals. For this material we must rely upon reference works and commentaries. You can understand that very very few people would buy a book with this material and therefore noone is publishing every new item as it comes to light. Students of paleolithography and ancient culture studies have access to more than most of us. However, if you ask at the library they may even have Prichard's books.
I am still troubled by your disinterest in the NT sources though. This is after all more pertinent to your faith. If you have carefully examined the site seedy first offered and you have no questions why have you not sought to discuss your spin of this material? Are you baiting us? Is it your intention to draw attention to differences in the stories to downplay the similarities. Doing so without having a feel for ancient mythology and religion would reflect only an arrogance that you in a few days know more than professors who have studied it a lifetime. Being we have tangoed before you understand my suspicion. If I am wrong please forgive me and ignore this last paragraph.
