Emotions are outside the realm of science. If you can't quantify or prove something, but are somehow experiencing it anyway, it falls right into the realm of the subjective.<quoted text>There is plenty of scientific proof for the existence of emotions and jealousy specifically.
None for god. Plenty for god belief.
None for the jealousy demon. Plenty for jealousy.
Your feeling of jealousy is undoubtedly different than mine, no?
In turn, my experiences with God are different than yours - you claimed to have had none.
*just like* trying to convince a child(or anyone that's never experienced it) what jealousy is all about, how it manifests, how it feels & how to try to control it.
