Someone (maybe Benjamin Fulford) said there were already 2 nuclear wars on Earth. These might be the ill wind from the explosion of the space port on the Sinai Peninsula, and the Mahabarata war. Anyway, they found glassified sand in the Egyptian desert that they say can only be formed in a nuclear explosion. Sorry I can't cite my references. I just think there have been civilizations for a long time that get destroyed somehow. Zawi Hawass is a gate keeper. Don't know why they don't want us to know unless they want to control and own us.
