Now, how does this galactic Neptune-Uranus theory relate to Orion - OCT's reference to the constellation of Leo etc. Well, when Earth, Neptune and Uranus align but at the same time align with the opposite of the center of the galaxy direction then if we observe Neptune and Uranus at transit we will notice that they are just above Orion in the constellation of Taurus. The issue though is to test if OCT is correct with it reference to 10500 BC and how this explains the role of the sphinx as the constellation of Leo. Well in my previous post I showed how the sphinx tail encodes the time it takes for these planets to align with the opposite of our galaxy direction and relate thus to Orion. But where does Leo come in? The constellation Leo is on your left - East when looking at Neptune transit. But as shown below if we find the date that is closest to Bauval's 10500 BC - this date is March 29 8976 BC then Leo is well over the horizon. On the other hand though if we consider the orthodox chronology for the Giza pyramids to have been built on the Neptune - Uranus - center of the galaxy alignment of 2466 BC, then the next time that these planets align with the opposite direction this time is June 17 576 BC. As we can see below at this exact date and at Neptune transit we notice that in the East the constellation of Leo will just have risen over the horizon - it's last star Denebola has a 5 degree altitude. Thus Leo is in the East and the sphinx is looking East. Also the wordnumber value of the Hellenic name sphinx encodes the distance between Earth and Regulus in light years.
The conclusion is that the architects of these structures wanted to encode the sky conditions of the next alignment after the pyramid age - a date that coincides with the rise of the Hellenic civilization and the founding of the racing events with stadiums being designed to encode astronomic information. Thus we have: 582 BC Pythia agones, 580 BC Isthmian agones, and 573 BC Nemea agones.
