There's no "neither!" option on this one. You have to pick. Would you rather plunge from an airplane with a parachute on your back or from a bridge with your ankles bound to a cord?

Advanced Civilization (Aliens)

There is one principal argument for this theory, and its that researchers and scientists alike say it just wouldn’t have been possible for humans to build the pyramids when they were built. The Pyramids are over 4,500 years old, and back then engineering was relatively basic, making the task of assembling such huge polyhedrons, Herculean. Even more interesting is the pyramids astronomical configuration, which is said to align with the stars in Orion’s belt.

Stone Carving Theory

Self Explanatory...

Causeway / Ramp Theory
Some theories suggest that causeways were used to haul the stone blocks on wooden sleds up the side of the pyramids. According to this idea, the ramps would have been lubricated, and as few as 10 men would have been needed to drag the stones up the ramps. Once the stone block had reached its intended height, wooden rockers may have been used to maneuver it into position.

The Wooden Crane Theory
Another theory is that as the pyramids were built with levels, the blocks would have been lifted from one level to the next. A wooden crane with a counterweight would have been used to hoist them up.
