Here is a summary of how specialists look at the possible astronomical orientations at NP:

“By the 5th millennium BCE these peoples had fashioned what may be among the world's earliest known archeoastronomical devices (roughly contemporary to the Goseck circle in Germany and the Mnajdra megalithic temple complex in Malta). These include alignments of stones that may have indicated the rising of certain stars and a "calendar circle" that indicates the approximate direction of summer solstice sunrise.[8] "Calendar circle" may be a misnomer as the spaces between the pairs of stones in the gates are a bit too wide, and the distances between the gates are too short for accurate calendar measurements."[6] An inventory of Egyptian archaeoastronomical sites for the UNESCO World Heritage Convention evaluated Nabta Playa as having "hypothetical solar and stellar alignments."[9]

Claims for early alignments and star maps

Astrophysicist Thomas G. Brophy suggests the hypothesis that the southerly line of three stones inside the Calendar Circle represented the three stars of Orion’s Belt and the other three stones inside the calendar circle represented the shoulders and head stars of Orion as they appeared in the sky. These correspondences were for two dates – circa 4800 BCE and at precessional opposition – representing how the sky "moves" long term. Brophy proposes that the circle was constructed and used circa the later date, and the dual date representation was a conceptual representation of the motion of the sky over a precession cycle.

Near the Calendar Circle, which is made of smaller stones, there are alignments of large megalithic stones. The southerly lines of these megaliths, Brophy shows, aligned to the same stars as represented in the Calendar Circle, all at the same epoch, circa 6270 BCE. The Calendar Circle correlation with Orion's belt occurred between 6400 BCE and 4900 BCE, matching the radio-carbon dating of campfires around the circle.[3]”

We can note the differences in how archaeologists, who are not trained astronomers, and an astronomer would look at NP. In general, archaeologists take a conservative view on the astronomical orientations and the astronomers saw all kinds of connections.

People can take sides on all this but I think both sides have a case. I say “Vive le difference!”
