I posted on the Atheist Nexus a few weeks back looking for stories that are in the bible and parallel stories in other mythology so I could introduce them all at the same time. The truth is that I don't know the religious stories myself, so I have no idea where the similarities are. I got some really awesome responses with links that I thought I would share here.
The Institute for Humanist Studies weighs in. There was only one book recommendation there though, In the Beginning: Creation Stories From Around the World by Virginia Hamilton. Part two is here.
This book list covers a variety of topics, not just similar myths. They are arranged by age appropriateness, which is very nice.
Mything Links has a lot of cool information on various myths from around the world. It is sort of hard to read and you need to scroll down a bit before you get to the bulk of the links.
This looks like the book I was looking for, at least an adult version.
A website full of link to different myths and legends.
Don't Know Much About World Myths by Kenneth C. Davis. Now this one is geared for kids, albeit older than mine. There is a preview here.
Most of these links I got from Saint Fillian, so I need to offer a huge "Thank you!" to her for helping me out.
If you know of any good book or website recommendations, please let me know.
