realizing the life

Guys here are 4 words:
Atheism, Theism, Agnosticism and Religion

The boundaries among them isn't crisp. Interpretation of
these words varies person to person.

Here r meaning of these words according to me.
Please help me out to break fuzzy boundaries.

Atheism:
Belief in no God

Theism:
Belief in God

Agnosticism:
Ultimate truth can't be found

Now here comes "God". What word God means. Its
quite difficult to define it, its meaning also differs
person to person. Then comes the religion.

Religion:
Generally meaning of religion is supposed to have faith in God.
But religion in real sense means to find out the truth. Its a
method, procedure to find the truth. Now there can be many
procedures which lead to same objective. So there shouldn't
be any conflict among religions.

Here's another big question:
After all, what's the need of religion ? Why should we find the
truth. There's utter need of religion because:
We born, we live our whole life with many different objectives.

If we achieve certain objectives, then we switch to other
objectives. Life goes on until death arrives. At the end of life,
we couldn't understand the purpose of life. We won the game of
life or lost it, no one knows. Even more clearly we don't even
understand the criteria that decides what constitutes "winning"
and what constitutes "losing".

From this overwhelming confusion starts the journey of religion.

"Whatever may be the position of philosophy, whatever may be
the position of metaphysics, so long as there is such a thing as
death in world, so long as there is such a thing as weakness
in human heart, so long as there is a cry going out of the
heart of man in his very weakness, there shall be religions."

One more thing:
It's generally claimed that if someone has found truth, why he
is not proving it ?
We should realise that proof requires language/symbols.
And language doesn't hold capacity to express every
concept/idea. Can we express "taste of apple" in words
without eating it ?
Our own experience is must to grasp compleletely.

Atheist : What is meant by your God ?
Theist  :  I am not sure, may be God is creation or the
             existence itself.
             It's not any individual identity perhaps.
             Upto this interpretation of God almost everyone
             will agree. Do you agree ?

Atheist : In that case, you are an atheist & not theist.
Theist  :  No, not at all

Atheist : But as per your God conception ??
Theist  : There is a big difference. You guys don't
             practice religion. But I do

Atheist : What do you call a religion ?
Theist  :  Good question.. By religion I mean to find the
             truth of this universe, Or to find whether so
            called "God" exists or not? And what's its form?

Atheist : But what's the need of practicing your discovery.
Theist :  Ok..
             We born, we live our whole life with many
             different objectives.
             Sometimes we achieve certain objectives, then we
             switch to other objectives. Life goes on until
             death arrives.At the end of life, we couldn't
             understand the purpose of life. We won the game
             or lost it, no one knows. Further we don't even
             know the criteria that decides what constitutes
             winning and what constitutes losing.
             From this overwhelming confusion starts the journey
            of religion, my friend

Atheist : But no one has ever succeeded in this quest.
Theist  :  How can you say that ?

Atheist : Simple, if anyone had succeeded, he must have shown
             to each one of us with proof.
             So many religious people are there, did anyone prove?
Theist :  The reason for that is the limits of logics, languages,
             even if someone know the answers, there may be
             difficulty in expressing answers

Atheist : What are you talking about ?
Theist :   Hmmmmmmm....Suppose you smelled a flower, whose smell
              is not smelled by your friend, you can't express the
              feeling of the smell using words/languages unless he
              himself witnesses the experience of that smell.

Atheist : But what's the need of all that ??
Theist :  Whatever may be the position of philosophy, whatever
             may be the position of metaphysics, so long as there is
             such a thing as death in the world, so long as there is
             such a thing as weakness in the human heart, so long as
             there is a cry going out of the heart of man in his very
             weakness, there shall be a religion or faith in God.
