The trip you had was different than what people experience on LSD or psilocybin. You still had a trip. You broke out of your normal frame of mind and were able to comprehend things from a perspective that you couldn't previously conceive of. It seems to me like this is the important component and not whether you think you met God or your creator. It seems to make sense that the changes in yourself afterwards are due to the experience and not to the chemistry, and I wonder if the people focusing purely on the chemistry have never had a trip.
