The science community will always have debates about ancient history. One of the most diverse debate is how various ancient cultures from around the world created the same type of massive structures when they had no contact with each other.
Science researchers have found massive pyramid structures in Egypt, central China, Mexico and South America. Some archaeologists believe that these ancient people found that stepping back stones to form a pyramid would be the easiest way to make a large structure because its base is wider at the bottom. However, others point out that the same people did not make pyramid shaped houses, granaries or other basic structures (went more to a box form of walls.)
Then there is a debate about what the pyramids purpose was to those ancient civilizations. Most believe that these towering structures were used as astronomical observatories to align important cosmic events such as the solstice or equinox to the planting or harvesting cycles of the land. Many believe that these structures served as the centerpiece of community rituals, including religious ceremonies. Other historians believe that some of these structures were made to show the power and authority of the king against his own people and other tribal rivals. Pyramids were symbols of power, wealth, control and status.
In Egypt, the consensus is that the pyramids were used as tombs for the kings. However, no modern science expedition found any Pharoah remains inside the pyramid itself; the temple and burial complex usually was found around the main pyramid structure.
The pyramids are tied to ritual beliefs. Apparently the Pharaoh believed, like any commoner among his people,
that every living body was inhabited by a double, or ka, which need not
die with the breath; and that the ka would survive all the more
completely if the flesh were preserved against hunger, violence and
decay.
The pyramids of Egypt, by its height, its form and its
position, sought stability as a means to traverse death; and except for
its square corners it took the natural form that any homogeneous group
of solids would take if allowed to fall unimpeded to the earth. The symbolic nature of the pyramid pointing to the sky, or aligned with the constellations, are clues to the ancient philosophies.
But most science teams cannot understand how these massive structures were built. Even today, with modern machinery and crane technologies, it would be very difficult for the 2013 construction crews to build a pyramid with such precision and in the time frame that the ancients completed their work. So the speculation is that the ancients had help or technology that we cannot comprehend. Pyramids are a lasting mystery hidden in plain site.
In LOST, we go into the walled temple structure with two outside court yards. We are taken into the magical pool inside the temple, where there are columns of Egyptian hieroglyphs which appear to be prayers to the underworld gods. But it is interesting to note, we never see an actual pyramid on the island. What happened to it? Or why was it not built? The people brought to the island once built the massive Taweret statue that was destroyed with the Black Rock hurricane ship wreck.
If the pyramids were the "space ships" for the spiritual soul to go to the underworld or heavens, then that could explain why there was no pyramid on the island: it was not needed. The island was the destination. Except, that does not explain why modern men who did not share ancient Egyptian beliefs, would have this island was their destination, alive or dead.
