again, what's more likely to believe?
Many people believe in many sort of different gods, spirits, etc and they all get "confirmation" of those beliefs everywhere they see. confirmations that imply others are wrong in their own confirmations. We can also replicate much of the "spiritual experience" in labs. Taking into account the many different beliefs and the number of people that adhere to them, seems that even if you choose one religion or belief, you are likely to be getting it wrong. You still think it is the most likely thing to believe that your position is the good one? Probably you might want to look out the window more often.
Sigh. I tried but you refuse to see. Just what evidence can you show that it is more likely that these experiences are chemical sensations rather than there is a powerful being initiating spiritual communication. You have not proven that just because the sensations are possible that it is the most logical conclusions nor have you proven that the two experiences are the same. You make the unwarrented assumption that your view is the most logical. You have not yet made a compelling case for that stance.
