There exists a theory, called the Orion Correlation Theory, which claims that the Egyptians built the pyramids to mimic the asterism of Orion’s Belt. Thus, the Nile River would correspond to the Milky Way. This theory was first publish in a book, The Orion Mystery: Unlocking the Secrets of the Pyramids, by Robert Bauval and Adrian Gilbert. This work provides a new perspective on the importance of astronomy to the ancient Egyptians. Anyone who loves ancient mysteries should give this book a read.
