World History Discoveries

I came across this article and wanted to share it with you all. These are potential world history discoveries upcoming in 2019. If these hold true they will certainly be revolutionary. Having taught 6th grade world history for a few years, the pyramid void is interesting to me and to kids. Kids always find Egypt interesting; especially because of the pyramids.

My question is: how did pyramids get built around the world without communication? Kids always asked me this question and I always thought, great question kid. You're asking me the question that I have wondered for years. However the mathematics that Egypt and these pyramid building civilizations helped us to develop are astronomical. I hope that you enjoyed this small post. Let me know what civilization you have enjoyed in the comments!
