"Extracts from Adam's Diary: Translated from the Original Ms." is a comic short story by the American humorist and writer Mark Twain.

"Extracts from Adam's Diary" was first published as a book in 1904 by Harper & Brothers, with numerous illustrations by Frederick Strothmann.

Adam (based on Twain himself) describes how Eve (modeled after his wife Livy) gets introduced into the Garden of Eden, and how he has to deal with "this new creature with the long hair.

He devotes his ironically scientific mind to demystifying Cain's species, thinking it a fish, then a kangaroo, then a bear.

The work does not consider God's role at all, and eventually, despite his initial deep annoyance with Eve, Adam finds himself in love with her.
