Only one God created this entire Universe!!!

Hindus say that Brahman is the creator, Muslims say
That Allah is creator, Christians say that the creator is
Jehovah, etc....
If Hindus say that Brahman created India, and if
Muslims say that Allah created Arabian countries and
If Christians say that Jehovah created the western countries,
The problem is solved, there can be three Gods together,
Who have created the three parts of the earth separately.

But this is not so, each religion says that their God only
Created the entire world, unfortunately there is one world!
One world only! Come on, all of you sit together here
and tell me WEN A CHILD IS BORN CAN ANYONE TELL WHETHER
CHILD BELONGS TO WHICH RELIGION.
Religions are rigid conservatisms! (to maintain the existing or traditional order.)
Even a small boy is putting this question to all of you.

Stop all your discourses and first answer this question.
If you want to say that God created the entire world,
You have to accept that there is one God only always
And that His names are all the above three names.
SO WHICH PROVES THERE MUST BE ONE WORLD RELIGION
