Just because people create these emotions in a state of consciousness, still doesn't prove they are having a real spiritual experience or actually connecting to these gods.It doesn't disprove it either. You just don't believe them, which is fine. Thomas communicated directly with someone who claimed a divine connection and also didn't believe it, until he received more evidence.
The christian claim is that God communicated to mankind through his word "Jesus". The validity of this claim was to be tested either through belief or disbelief in the resurrection. Christianity continues to the present day because people continue to believe in the resurrection of Jesus.Paul claimed that if Christ had not been raised then christianity is in vain and so concluded,"Let us eat and let us drink, for tomorrow we die."
