Okay, I'll give it a try.
For starters, there are two ways of thinking about reality -- subjective mental experiences and the objective physical realm. With legions of Christians relentlessly harping that "God exists," it seems perfectly logical to conclude they must be wrong, because there is absolutely no evidence of God's physical existence.
However, during my 1968 Hippie period, I was the guest of a commune of Haight Ashbury Jesus Freaks. We all took LSD and participated in group prayer. I soon had an amazing religious vision and clearly saw God within my mind's eye. God even explained to me that He is a subjective mental experience, which is why those who expect to find Him in the real physical realm are always disappointed. This made me recall the members of my childhood Pentecostal church and it was perfectly obvious that they were having a mental experience, shrieking at the top of their lungs and rolling on the floor while "filled with the Spirit." I suddenly realized I had squandered years searching for God in all the wrong places. God doesn't "exist" within the objective physical realm because He is actually a subjective mental phenomenon. If you are an atheist because there is no evidence of His physical existence, you have also been looking in the wrong place. If you want a genuine religious experience, consider that God only appears within people's minds and try fasting, prayer, and the company of convinced believers to achieve the proper state of mind. (These days, "magic mushrooms" are the only psychedelic still available that can loosen your grip on your perceptions enough to facilitate a religious experience. ...and yes, they are still highly illegal.)
These days, I consider myself a scientific atheist because God is obviously not part of objective physical reality, but that doesn't mean He can't be found lurking within my mind as an occasional subjective mental experience. I urge you to reconsider your approach and to NOT listen to the blowhards who will only lead you astray by insisting that God "exists."
