I enjoyed your post, but think it is a bit of an oversimplification to say Atheists exist primarily because they had a bad experience with religion. I understand why you would have that impression. It is often the catalyst that makes people want to look behind the curtain.
I have no desire to convert anyone to my way of thinking, but I also know that I am incapable of deciding there is a God because everything in the Universe is so amazing. On some level I envy your ability to believe in a God, but at the same time I think it requires a certain naivety. At some point there has to be a beginning.
If there was intelligent design then where did that entity come from? Even if there was intelligent design, does that automatically mean there is a God or just some really smart being who died long ago? Please understand that I respect your beliefs, and I seek no converts. I do however enjoy having a forum that allows me to have these conversations. Maybe someday someone will find the logic to convince me that God exists. Maybe someday I will find out that UFO's are here from another planet. I hope to always have an open mind about anything and everything, but in the meantime, I respectfully disagree with your assertion and hope you will continue to make your points. I've never understood why everyone thinks we all have to have the same beliefs. I think it is fantastic that we all contribute from a different point of view. The only issue I have is with religions who seek to promote their beliefs at the expense of mine.
