If we want more evidence we'll have to go to cultures that didn't leave a written record. What they did leave are called menhirs, monoliths, or single standing stones.

These monoliths were set up in ancient times around the Mediterranean and in western Europe. Here's one in northern France, in Brittany:

It's in 4 parts, was about 70 feet tall and weighed about 340 tons. This huge stone came from 50 miles away. You can see it had a pyramidion at the top.

The Hebrides off the coast of Scotland are wild, windy and wet islands, but they're quite beautiful. On the isle of Islay which faces the Atlantic ocean, there is a monolith. This one isn't broken, in fact it's still standing:

In the county of Devon, in south west England, on Dartmoor, there's a monolith. Some have been broken up in past centuries by farmers, who used the stones for construction, but not this one:

And there's another menhir in Yorkshire, in northern England:

The Christian church picked up on most of the old Immortal vestiges of religion. Churches were built on ancient temple sites:

The menhir was probably on this site thousands of years before the church was built there.

I suggest the evidence provided in this episode shows that the Immortals, or Celestials, were present in ancient times in north Africa, the Near East, north western Europe, and the subcontinent of India. It seems reasonable to deduce that they proliferated world-wide. The menhirs, or single standing stones, were, it seems logical to conclude, part of ancient 'temple' or 'house of god' complexes, thousands of years ago. One of the Indian writers referring to the Celestials of India tells us that the times their ancient records refer to are 'about 12000 years ago.'
