I don't know why people believe in religion (especially in today's world with the all information available few mouse clicks away) but I think it's their right to believe in whatever they want. For example I was raised in a family where my mother has been christian and my father has been atheist. Until I was 17 I believed in God and Jesus but after reading many books and documentaries I stopped believing. And it was on my own. Nobody forced me to believe or not to believe.
The most important thing is that whatever you believe in does not harm anyone. As long as you keep it for yourself and for your own spiritual good I don't see any problem. I know my mother finds strength in her belief so why would I try to convince her to stop believing.
I think that many people search for purpose in their life.
I believe also in the spiritual reality, not just physical.
Yes, scientists can create many ''nice'' things and our life is better now than before, but still many people feel''empty'' and without purpose of life.
Do you think that technology or science can give us purpose of life?
Or help us find ''inner'' peace in our mind?
I don't think so.
When we talk about God, we are talking about spiritual reality, and science can't help us in this area.
Technology and science certainly can't give us purpose of life. Far from that. But they are just "a tool" in our life if you know how to get the best from it.
For example, what bothers me the most is how people use internet in the wrong purpose. Instead of looking it as an unlimited source of knowledge many people use it for for stupid things which separates us from each other.
And I wouldn't necessary agree with you that technology can't help us in spiritual area. For example, if there was no internet I probably wouldn't ever try to meditate (which is also some kind of spirituality). You have access to people who can teach you what they know about spiritual, so you can open your mind to other things and not just something your parents taught you.
I think we are "by default" spiritual beings and that's why some people feel empty and have no purpose in life. That's why I said that as long as your religion doesn't harm others you can believe in whatever you want and nobody should ever try to convince you otherwise.
