What you did was change from something that most atheists accept could be true, the existence of God, to something that I suspect most atheists dont accept could be true, magical pixies. If most people accepted that magical pixies could be true then they should also accept that people could have experiences with them.
The same thing with God, if you accept that there could be a God, then logically you should accept that people could have experiences with him or her. And if people could have experiences with God then you should at least be open to the possibility that some of their testimony of experiences with God could be true. You shouldnt logically discount all testimonies of experiences with God as something other than that when you accept that there could be a God.
No, thats not what I did.
I accept that a god could exist in the same respect that pixies could exist. In fact, Pixies are more probable than a god, in my opinion.
I accept that their experiences with a god could be true, but thats not evidence for me or anyone else, thats there own personal evidence. It could be true, just like the magical pixies could be true. But I would not be justified beliving in a god or magical pixies based on someone else's experience. It's an extaordinary claim and would need substantial evidence to claim it's veracity.
If someone else's personal experience were enough to justify belief in that god. Why are you not a Hindu or a muslim? Other religions have personal experiences too, and you probably don't think their personal experience is enough to believe them for the same reason I don't believe you or anyone else who has a personal experience with a deity. The mind is easily manipulated.
