Story Similarities

I realize I am a little late on this but I did want to put this on my blog.  During the creation stories I did notice that the stories dealing with an earth diver surficed again and again.  But it wasnt this that struck me about all the creation stories.  What I noticed was that the closer the locations the of two myths originated from, the more similar they were.  I noticed this not only with native american stories,  but also with stories in the pacific islands and surrounding areas.  This makes sense, though, because these stories have been handed down by the art of story telling and as populations expanded, the culture, religion and beliefs went with them.
