Archaeoastronomy is the study of ancient monuments and their astronomical alignments to gain an understanding of ancient civilisations. Stonehenge falls into this category.

Interest in this subject has grown in recent years following a lot of new work interpreting the Great Pyramid at Giza in Egypt.

New theories for various sites abound, and those based on some sound research and facts deserve a greater degree of attention by the established scientists such as the Egyptologists. Other speculation (such as the suggestion that there are pyramids on Mars which has largely been disproved by recent space probe photographs) are far from having any sound evidence at this stage although further research is justified. At this stage we should avoid the sort of mass hysteria that led to everyone seeing non-existent canals on mars a few years ago.

Whilst keeping an open mind on some of the fringe issues the basic work on the Great Pyramids at Giza is my particular interest . The realisation by Robert Bauval and Graham Hancock that these monuments bear an identical relationship to the belt stars of the constellation Orion was the starting part and this work has been enhanced by studies inside the pyramid.

However these alignments indicate that it is much older than previously thought. Also the Sphinx shows signs of water erosion which indicates it comes from a much earlier time when the area was not desert. Pyramids are found all over the world so was there a very ancient civilisation of world proportions.
