The very idea of proving god is real moot, God is a faith driven idea, Faith at it's very core is throwing out logic to accept what you cannot prove. That being said, It's about how you decide to think about it. Religion is fundamentally a means of explaining the unexplainable through unobservable means, I.E an easy way to have answers for hard questions.

The only thing i can say that would convince you that god does not exist is the fact that we can prove several things happened through the scientific method that directly conflicts with anything that has been explained by religion like evolution and the insurmountable evidence that what created the universe is the big bang.

Believing in something which requires the ability to throw out logic is hard.

Personally, i see a pattern of tyranny and genocide associated with religion along with great efforts to hide the truth from people in order to keep their establishments alive.So not only is it untrue, but it is morally objectable to support something such as this.

No, drugs are part of human culture, and have provided incredible insights to the human psyche and the universe. They should get a Nobel prize

It is a logical conclusion based on overwhelming amounts of observable evidence, Religion makes claims to supernatural events that can be dis proven using the scientific method, That and religion is an outdated means of suppressing the fellow man. People are much more logical nowadays, and look for observable evidence of god's existence. To believe in god you must have faith, To have faith you have to have to ability to throw logic out and believe in the unexplainable, Unprovable, and non tangible.
