No matter how many times you have seen the pyramids on photos or on the tv, when you see them life their size amazes you. They are like small mountains!
It is not easy to understand how Egyptians could construct such huge monuments. Official books say it took them 20 to 30 years and 100,000 workers to erect them. Some other authors give other explanations: did gods help them? Were the extraterrestrial who helped them? Or were they built by giants? No matter how strange the version is, when you are in front of these pyramids you are open to believe it.
In this photo you can see the two biggest pyramids: Kefren and Kheops.
