How does the thought of a Creator fit into our highly-technologised society?

After growing up in a Protestant home but having never believed in a God as he is characterized in the Bible, I keep catching myself doubting whether we need a "God" in a modern society. Surely, a thousand years ago, people needed Religion, for it provided social legislation and moral values. Of Course, nowadays we need those things too, but i dont think that raging atheists will start burning people as soon as we stop going to church. We have Statute Books and Constitutions to make sure that people behave the right way today. But, without religion, some questions are left, such as: Who or what created us? Is there life after death? Is there an Intention in our existance?

Personally, I'm not sure about this matter. I do not know whether there is a Creator or not. In the Case that there is one, I doubt that we could ever understand it, or that "it" would be the same God we know from the Bible; it propably doesn't even care about us. If there is no Creator, we are a bunch of unimportant mammals floating on a rock through space, unlikely to ever do or find something really crucial.
On the subject of Life after Death, there are a lot of reports of people who have nearly died and all had Visions of heaven-like Creatures and total happiness. Again, I do not know whether they really were on the step to a new form of existance, or if it just was a backlash by the Brain, trying to ease itself from the total certainty of Death.
So... do we have a Purpose in this world?

I think we do. And I also think that it has nothing to do with our Creator or where we come from. And that is the message i want to get across: Before we start blowing our own Horn about how awesome we are or start wondering about unimportant stuff like what happens after death, maybe we should think about what happens before that; we should finally change something about us. There is no difference between us and the people 2000 years ago: We still hate each other because of our skin's colour, People still kill each other, steal, rape and wage war.
So if you need a rolemodel like a "loving, almighty God that always watches you" to do that, then go and pray, but don't try to shove it down other People's throats.
Everyone should have his own choice whether he wants to believe, and in what, or not.
