I just finished reading the personal diaries of Eve and Adam - you know, the original humans. It would appear that Mark Twain discovered the original manuscripts and succeeded to translate the ancient hieroglyphs somehow (perhaps he used a top hat) and published them to the world. I will be the first to say that we are truly indebted to him. I can't imagine why this wasn't included in God's book - maybe the publishers wanted him to save this material for another book.
A general disclaimer: No I do not believe this book is true. No I do not believe in the biblical story.
Eve's Diary can be found in a beautifully written and presented e-book here. It looks wonderful on my Kindle. A public domain audio recording of the work is attached to this post, but I warn you that I have no idea what that means. So you can download that for your Ipod here.
The book contains beautiful illustrations Lester Ralf, which apparently got the edition banned from a library in Charlton, Massachusetts banned for the depictions of Eve in "summer costume." Naked Adam was apparently not offensive. Twain's response (to Congress, no less) is genius.
