"Why do you assume creation is a myth?"
Well, let's look at that question. Every religion, from the smallest native American religon to the largest religion, has a creation story as part of that religion's teachings.
They differ largely. Maybe one says the Crow created the universe. Another has a Coyote. The Hindu religion, as old as Judaism, has three versions of creation, all related, but somewhat different.
My guess is that you would classify all of those as myths. Yet, your religion's story of creation is correct? Sorry, I just believe that your religion's story is a myth, just like all the others.
You may, if you wish, present some argument to demonstrate why your religion's creation story is more valid than that of, say, the Chumash Indian creation story.
I'll be waiting.
As an atheist I wouldn't expect any other answers from you, which we have heard over and over and over....
Since you are an atheist, it is understandable that you don't want anything religious taught anywhere. As a Christian, I have the same rights as you and can send my children to where they will learn the truth.
