why can't we have a mono-religious world?

Day by day all I see is religious differences
A set back of the old colonial era
The making of jest and playing of people as chess
where do I turn to?
who do I find the old forsaken shaft of unity?who will listen to my song of' let's be one for a better tomorrow'?
everyone is busy with economy,Jeopardy and yet vanity.
should I meet Judaism,Hinduism,Islam,Agnosticism or Atheism?
Should I be worried about Salah or Dua?
should I perfect my prarthana or mantra?
who will reach me Tefillah?
how can I pray this prayer of an agnostic that says;
"Insofar as I may be heard by anything, which may or may not care what I say, I ask, if it matters, that you be forgiven for anything you may have done or failed to do which requires forgiveness".
what if I want to sound like an atheist,should I pray like this:
"May all beings have happiness and the cause of happiness. May they be free of suffering and the cause of suffering. May they never be disassociated from the supreme happiness which is without suffering. May they remain in the boundless equanimity, free from both attachment to close ones and rejection of others".
Who should I support?
where should I belong?
which is the best?
what should I believe?
No! enough of the questions and dancing in my head.
how am I supposed to choose what religion I want to believe in when I know Jesus is dead!
But no,he is not dead!
he is alive!

that's where I wonder how a man can live only to die and die only to rise again from the dead all for my sake?
My Islam mind tells me, that doesn't make sense. 'Mohammed is the true Messiah and prophet of Allah!'
I am pure by the teachings of the Imam!
I make sure I sanctify myself by 'washing' before praying to Allah.
I do my Azumi and meet up to the standards of a true Muslim.
I pray to Allah by...
