Most Americans and people around the world disagree with you. There are many things beyond our current understanding, I do not agree that just because you cannot see God, there isn't one.
Take, for example, meditation. When you meditate, you separate yourself from your body, relaxing each part of you and imaging disconnection, starting perhaps with your feet or hands and moving on from there. 
A part of meditation is to separate yourself from your mind, which is also a kind of a muscle, constantly sending out random thought in no particular order. Those who meditate find it peaceful because they have learned to separate their brains' thoughts from themselves. 
I have found it amusing to ask after this: 'Who am I?'. So who do you think you are? Where do 'you' sit in your body if you are not your brain? So if we are not our bodies, who are we? Where do 'we' go when our bodies are no longer functional. I prefer Jesus' view, but many others have different opinions.
