Who really built the pyramids?

Our education system creates a limited understanding of even the greatest aspects of our history. School history books still equate pyramids with Egypt alone and illustrate them being built by slaves pulling hand quarried blocks to build them. Few people who have not carried out their own research realise that there are pyramids right across the globe all built to precision and size that even archeologists have to admit is NOT POSSIBLE to replicate today! What happens when we look at the bigger picture of the similarities between these supposedly separate civilisations? The fundamental idea that underlies our culture today....that the evolution of consciousness on this planet is linear and that we are the most advanced civilisation that has ever inhabited earth begins to fall apart.
