I strongly believe that God is only a mere creation of men. Most humans are naturally weak, they offer themselves to the slave morality, meaning that since they suck at everything, they make traits like being humble to the next level, and make them "godly" qualities. And besides, most of the people on this earth cant comprehend life without a supposed god, because to them it revolves their little worlds and helps them sleep at night, which is great for them because they are out of my hair. But lets be honest, God, religion, and everything associated with it is man-made.
Another reason I believe this is because people need an explanation for the unexplainable. For everything that they cant explain, evolution, the big bang, etc, the religious platform has to come back with an explanation of their own, and God serves that purpose for them, and as sad and pathetic as this next statement is, its also very true: I once knew someone who believed that the sunsets, sunrises, and rainbows were created by god, and they were 100% gods doing. Now of course, no surprise this ignorant human being will not see secondary education, and Im sure you can see why. People need something to explain the things they cannot grasp, and god or religion is definitely the number 1 answer to use.
I also find that arguments made for the God created man case, are very pathetic and very very weak. Well first off, someone said below that the bible was all they needed. I find this hilarious and also alarming because how did you get to do things like learn to read or ride your bike, because they arent in the bible, so it seems to me the bible is the last thing you need, unless of course you live a life of blind faith and it warms your little heart at night when you think about god.
And to the man who said Creation is NOT an accident, blah blah blah... Who ever said creation was an accident? Evolution is actually the farthest thing from an accident as you can get. Millions of years of tedious adaptation to become the strongest and thus the most likely to survive in a given environment couldnt be further from an accident. Actually its funny because, I consider the story of creation more of an accident, well adam and eve were dropped from the sky, hmm, dropping, falling, all those words would work really well with accident, including your answer.
