Well i remember praying when i was a child but even then it always felt like a hollow action.  As I have grown older I have come to understand that feeling a little better.  Even as a child i never felt any kind of presence within myself that was not me and no presence outside of self that wasnt directly attributable to another person.  In effect what I am saying is that while I believe there may have been some greater being than ourselves who may have played a role in the creation of the universe as we know it in our limited fashion.  I have to date never experienced anything that in anyway gave me even the slightest indication that there was a god out there( in the sense that i understand all religions teach).  I have looked into every religion I could find information about and at their core they all seem to say the same things ( with a few diametrically opposed exceptions) mostly that you can give over all your troubles and not worry just believe he will handle it for you etc etc.  I prefer to face life with a clear rational mind and try to get as much information as i can so that any decisions i make will be as informed as i can make them.  I understand that no matter what (according to all religions, no exceptions i could find) that in the end you and only you will be held responsible for every decision/choice you made even the ones that you made by choosing to not make one or not face the situation you were in.  I have never believed in original sin simply because it made no sense to me.  How can I be held responsible for someone else actions or decisions that i could not possibly have had and effect on.  
sorry I ran on so long  
This was a very hard thing for me to reconcile when i was young and much to my frustration it is still not totally resolved, i do not see much chance of it being resolved before i reach the end of physical existence. I expect that if there is existence other than physical existence I may have more information that may help resolve the issue of god and religion until then I only allow for the possibility and that is why I do not pray.  I do have internal conversations with myself about every issue and choice i face.

yes i like to pray every day n i thank god every day 4 the things i have n dont have lluvia
