It is not for humans to decide whether is there a god or not. The existence of god must be something beyond of human mind. For example, people have domestic animals or pets. People feed them, and watch if they are okay. But can an animal think of people’s problems? Are they capable of understanding them?
I believe it the same with god. If god exists, people won’t be capable of understanding his mind. Whether he exists or not, it makes no practical benefit. We don’t see god’s interception to our world. Even if he exists, he sits still and watches. So should we care does he hears us or not? Our time is limited and we should worry more about our lives and real problems. It would be too unfair to do nothing as a god, and wait that people will follow his rules. If his goal was to make us what we are, then why does he expect so much from people? Let’s be honest and accept that god has nothing to do with us.
So why care?
