The gods were created by men in an attempt to explain those things which they were ignorant about and unable to control, such as storms, earthquakes, volcanos, and the like. As our understanding of the natural world and the universe at large has grown, the need for having supernatural creatures to explain things has diminished. The advent of the home computer and the internet, bringing unprecedented means of information to virtually everyone everywhere is allowing great strides in understanding our real place in this universe, and the growing desperation of religions trying to maintain their hold on people's minds is allowing people to see those religions for what they really are. I honestly believe that, eventually, the greatest part of mankind (except for a few fanatics and idiots) will toss off the shackles of religion and realize their true potential.
I have faith in us.
