Can anyone explain Ley Lines?

Question

What are they?

Answer 1

Ley Lines are part of the electromagnetic field of the Earth and create a grid around the Earth.

Answer 2

Ley lines are alignments of a number of places of geographical interest, such as ancient megaliths. Their existence was first suggested in 1921 by the amateur archaeologist Alfred Watkins, whose book The Old Straight Track first brought the phenomenon to the attention of the wider public.

In other words, Ley Lines are thought to be alignments of ancient and sacred sites, such as Stone Circles, churches, burial grounds and megaliths, and are considered to be sources of powerful earth energies.
