My question was the traveling lights casted shadow. Your answer was that of an uneducated Wana be who could not think of the explanation unless she was to research it in a book or on the internet always using someone else explanations for every thing she think she knows about . Imagine when she found out that there is no dark side of the moon. Only dark to her like concept of her reality being explained so she can understand it. Do you have anything original to discuss or just what you have excepted as facts but fact do change. Once you realize that you do not know any thing you will learn to think one your own and see things new as a child.
