The Ancient Egyptians believed that after mortal death the soul or spirit would continue life in another dimension. They buried their Pharaoh kings, whom they regarded as living Gods, with all the treasures and objects needed to survive in comfort in the afterlife.

They also embalmed their bodies to ensure that their mortal remains would be mummified and preserved for whatever fate awaited them.

Crucially, they built impressive burial structures to demonstrate the dead person's importance and to aid their ascendancy to the next dimension in the heavens.

The most famous and enigmatic of these buildings are Egypt's pyramids, and the most mystical of all these is the Great Pyramid of Cheops at Giza. However, many people question whether the structure really is just a simple, albeit awesome, tomb or whether the design holds one of the great secrets of civilisation.

The pyramids were erected between 2800BC and 2200BC; the first was built by King Zoser in Saqqara near Memphis. Although the structure was created with six stepped tiers, and is not a strict pyramid as such, it was the first building designed exclusively to house the property and remains of the king.

In the following centuries King Seneferu built his own trio of pyramids. One at Maidum was called the 'False Pyramid' because it was abandoned mid-project due to a structural weakness. One as Dahshur was known as the 'Bent Pyramid' because of another design problem which meant the gradient of its sides had to be reduces as it was constructed.

The final one, called the 'Northern Pyramid of Seneferu', was built close to the 'Bent Pyramid', and is recognised as the first true pyramid.

However, many people in the world question whether the world of Ancient Egypt had the means needed to build the three great pyramids that stand on the ground today.

Some claim that is was an act of God - who placed a pyramid to point up to him. To show his greatness and superiority.

Others claim it was an Alien related phenomenon - that the Aliens built the pyramid and placed it into the desert pointing to their home planet, or used the pyramids and landing markers.
