In 3,000 years people will be astounded at what you believe today. You can't bring an ancient belief into the modern age and ridicule it because it isn't modern.
The first caveman who painted an animal on the wall of a cave likely set in motion the first abstract notions of something beyond the physical grind of life.
3,000 years ago we didn't have electricity, planes, open-heart surgery, but they existed in a potential sense. Belief in God is no different. We start off painting on a cave wall and progress through levels of understanding that look ridiculous in hindsight but if we view religious history with a just eye, one can see progression.
Sure, there are people around today who still apply the most primitive, literal interpretations to this stuff, but in the fullness of time it will be seen for what it is.
Religion deserves no less respect than ancient scientific understanding and historical beliefs. What we believed about God thousands of years ago is not a definitive understanding it's a beginning. What we believe in the future will be so much more refined, making todays beliefs seem a bit odd.
So you haven't discovered a flaw in the system all you have done is shown that we are on a journey of understanding and we have a long way to go.
