These pyramids should be preserved, although with us not knowing how they were built makes me wonder why we would take with us something we cant explain how it exists.

The purpose for the pyramids alone is a great reason to consider its preservation for the religious and political reasons. Pyramids created for the Gods and the kings represents the triumph of these nations as unique civilizations with uncanny knowledge that lasts to this day.

My question for you, is as the pyramids are still a mystery to this day, what most impresses you about the pyramids besides their ability to stand the test of time and exist in 2011
