Is it just the grave?
The pyramids are about 4,800 years old. There are still so many mysteries. Some believe that it is just a tomb. Some claim that it is used as a generator. They can also be used for multiple purposes! Let's think a little... As far as we know, 4,800 years ago there was no advanced construction machinery like today's technology. Did people carry those rocks all the way? In ancient times, maybe some technologies were far superior to today. If you could go back 4,800 years (some say it's possible if you go faster than light speed away from Earth and look at Earth) what would the pyramids look like?
