It really depends. Some people believe there is a god, mostly because they need that kind of comfort because they are going through a time of stress in their life. In fact many scientists believe in god, mostly because though they can explain a lot, they look more towards that there was a creator.
But i see your point. Maybe you feel nothing, like no influence by a godly power, which true christians would call you a sinner. But most people believe in the science side. most don't believe because how can their be one god if there is so many faiths with so many gods?
i guess that's what everyone wants to know. But all people can do is state their beliefs, like for me, I'm struggling to see proof god exists, like the bible could have been written recently, not many years ago. Also i haven't seen "god work in my life" and that their is many other faiths with different gods. Im slowing straying away. So at this point
