I don't know if i trust the translation honestly. I have doubts about the bible translations as well. That is a very important point that you brought up. With the Sumarian tablets and Old sumarian mythologies we do however have ancient pictures to go with as well. Zecharia Sitchin did a translation on the Sumarian Tablets, But The University of pennslyvania and Oxford University has taken on the translation as well.

But this is what really gets me :
Sumerian tablet translation calls for re-examination of Genesis text.The familiar biblical story of the Garden of Eden compiled in the 1st millennium BC has had many counterparts little known outside specialist circles. One however was written in clear and secular terms and inscribed on clay tablets in Sumeria during the 3rd Millennium BC and placed in the Nippur library.

Now published in the book The Genius of the Few by ancient languages scholar Christian and Barbara Joy O'Brien and available for inspection on this website, we now have within An Alternative Genesis the contributions from a much earlier and more detailed record providing the self evident links to the Bible.
