Wow! This is very interesting information, @ladyrebecca. I didn't know it at all! I have always been struck by the discoveries of prehistoric pieces that can help us not only to know the lifestyle of our ancestors, but also to explain our own behavior. The fact of knowing such an ancient astronomical observatory tells us about the intellectual capacity, the advance or scientific development of our ancestors, for example. In the same way, the shoe. This piece indicates the ability of our ancestors to solve everyday problems such as protecting their feet from mistreatment. Excellent post. I liked it.
