Exactly relating with my country India. Those people praying to a shape is an exact match with Hindu god Lord Shiva.

That sculpture called Shiva Linga. In India we worship him as the creator of this universe
Reading your post triggered me the resemblance. See these reference photographs:

Ref 1: Front view

and
Ref 2: this is might ring some bells - Top View

I feel these are my valid points of making comparison:

1. Both side on the stone sculptures people are praying (that was the gesture used in Hindu mythology to pray),
2. The shape and the way sculpture is an exact match.

You can search in Google as "Lord Shiva Lingam" for the pictures i posted and for the god, here is the wikipidea page
