The New Age viewpoint is a loose term we have used to summarise a spiritual input. Religion for want of a better term in Neolithic times had similarities to pagan religions nowadays. The concept of Mother Earth and Father the Sun overlap to some extent with the Archaeoastronomers viewpoint, the concept of 'energies' and the siting of Stonehenge at the intersection of many Ley Lines also follow a back to nature theme.
Today the Druid religion uses Stonehenge as a key religious monument, though druidism itself wasn't around at the time of the Neolithic's.
