the point:

In Skywatchers, Shamans and Kings, American astronomer Edwin Krupp states that the centre in all cosmologies marked the place ‘where creation began, where order and life first emerged.’
This explains why many world centres are often referred to as ‘the navel of the Earth, the point at which creation began,’ says Mircea Eliade.
Stones or other objects such as golden rods in Cuzco, the ancient Inca capital, or meteorites in the ancient Egyptian city of Heliopolis (now an outer suburb of modern Cairo) marked many of these so-called ‘centres’ of the world.
The ancient Greek name for these marker stones is especially revealing, for omphalos means ‘navel’. Given this link with creation, it would be interesting to discover how many of these centres have an association either directly or indirectly with the stars of the Pleiades. The omphalos at Delphi may be one of these.
