Some atheist are open to the idea of the supernatural, but understand that the supernatural cant be tested or is even proven to exists.
Did you watch this video? He specifically states that he was under the affects of MDMA. Of course you might experience something out of the norm on drugs. Also, how to you connect the behavior of you brain on MDMA to a God?
Both these points I addressed in the same manner. I fear you are being dense on purpose.
I said Atheist believe the supernatural fall in 3 categories on a case-by-case basis: it can be either false, coincidence, or unexplained.
I said Atheist believe "spiritual/metaphysical experiences are possible absent the existence of God." Therefore they would never attribute anything to God.
