Hello again,
                I think we may end up arguing semantics, or there could be a language barrier between us, so I would like to be clear about my beliefs.
I consider myself a spiritual individual...not a religious one. As a result, my spiritual beliefs differ from those of religionists. I know that the word "Spirituality" has taken on a disreputable meaning. Charlatans, magicians, and psychics are but a few of the derogatory descriptors. Some even call spirituality "new age mysticism", although, most spiritually based practices, like Paganism for example, pre-date most known religions...if not all of them.

For me, spirituality is...awareness. It is the realization that all of this was created; That there is a Creator; That we know absolutely nothing about who or what that Creator is.
For me, religion is the opposite of this. My belief in a Creator is not synonymous with religion. Is it necessary that one be religious to believe in something greater than himself? I do not think so.

As to the question of necessity...it is not necessary for me. My life has been decided by my own choices therefore, there is no need for me to look outside of myself for direction. I choose to explore my spirituality because I think it connects us to this planet, to each other and to the universe itself. We are made of the same stuff and that intrigues me.
As to the question of God...I do not believe in the conventional God of scripture. As I said, I know absolutely nothing about what or who created all of this. I simply know that it was created. I base that on a rational line of thought that I will explain, if I may?

I posit that existence is the antithesis of non-existence. Existence, then, cannot simply spring forth from non-existence without an external influence. Therefore, something created existence. I do not presume to know what or who that was, only that it is so.

The importance of a God then does not matter to me since my belief rests on the postulate I mentioned above. I believe that everything was created...whether that was by what people refer to as God remains to be seen.

People will always believe in religion regardless of what happen. If they do not worship a diety the will worship things or other people. That is the amazing the about human. Perhaps you should question why people had the tendency to worship.

as for me, everyone needs religion as me myself do believe in the existance of God. furthermore, its the only way that can truly unites people from diffrent races and background of life.
after all, religion guides the everyone away from wrongdoings, if only they do really devoted to their religion.

So how about the evil in this world, the atrocities and crimes humans commit? Where do they come from?

'people who can think properly needs religion.'

who are we, where we come from, where are we going etc questions =)

in fact, many people get psychological support from religion

Whether God exists or not does not matter, what matters is why God exists.

religion is not a human made tool as some would think of. It's already planted as a way connecting humans and the other dimension. It can be hidden, or revealed to humanity. Whatever that I speak now is something acknowledged to me.

it's either the religion will serve as humans knowledge or didn't attract them.

So your logic is that if an establishment supports false information, even though people know about it, they should keep quiet and be obedient? Religion is big not because of the information it presents, but the amount of people that supports it, even though some of the information is not logic. By presenting factual information, more and more people will reject the superstitious part of religions. Atheists have been growing due to these information. However, there's also a problem with atheists because they reject religions blindly without consideration of humane values, and they don't respect religions. That's why a neutral and humane approach must be used on religions, for the benefit of everyone.
