Who created Religions, Castes, Groups etc.,?

Either God Created Religions?

or Religions created God?

If God is the Real Creator of everything,
then,
Who must have Created other religious people,
who worship their own Gods?

If we honestly believe our God,
as true God,
as one God,
as one and the only God,
then,
He must be The Creator of other religious, worshiping their own Gods people too.

If it is so, then, they must be our people.

...Perhaps their own God Created them...?

If it is so, then, we must admit their God also.

Let us decide and admit one factor!

Either All Gods must be One 

or all the people must be
our own people!
