I can still see why people belive, there are things we can't explain and products we can not duplicate. Take blood for example man still can't duplicate the ability of the red blood. The reason so many become atheists is because once we awaken from the JW world we become very critical and with all the problems we find in the bible and proof of evolution just to name a couple of examples, it becomes obvious that there's a big problem with our idea of God. I also can't rap my head around this idea that a loving God would let mankind go through the suffering we have.
I believe there maybe a god but that this God just planted life here and maybe made things like the laws of the universe but he does care about us. That's where I'm at with my belief system anyway but it may change again in a week.
