One episode of something interesting to learn about, which was something to see. It was quite interesting as to why Egyptain or Spanish people would create something that was four sided. I would only think that they would live in there or do something in there. Although I knew that it had something to do about the location and something about worshiping. But to hear it again, really made me feel like I learn something extra, in fact, it was really cool they knew about the stars and where to put structure at the right location, while it took us technology to find this out. They must have been smart.. but guess what.. another guess was that it had to do with aliens again! Do you believe it or not? Got any comments that you want to share? Feel free to response and interact with this mystery!
