Dear Scholar
It has 2 parts
1. God is not a mathematician. He is a Geometrician . To be more accurate God is a Cosmimetrician. This author read Mario Livio's book" Is God a Mathematician".
Geometry is older than Mathematics
Geometry is the study of the Earth
The Earth is part of the Cosmos.
All Planets and Stars are spherical in shape
So, the Geometry of Planets( including the Earth) and Stars is Cosmometry.
Hence it is more apt to call the God as Cosmometrician.
Part 2
Who is God ?
Who is man? Let us ask!
He is basically made of elements like carbon, hydrogen, oxygen, nitrogen etc.,. so, his body is systematically organized physical entity.
Man has thus later acquired the mental faculty " thinking"
Cosmos is an organized physical entity just like the human body at micro-cosmic level.
We have the capacity of "thinking"
Similarly, Cosmos has an in born "God"
In other words as thinking in man so also God is in Cosmos.
to conclude: God is a COSMOMETRICIAN
