if a higher power dont exist, close your eyes and use your own mind to turn off your heartbeat
You really can't. The heart beat is an "automatic" function.
Trained meditators can lower their heart rate, but not stop it.
if one could control everything...they could stop their heartbeat...
whether you like it or not...God/Supreme Creator exists...
So the fact that you can't control everything proves god's existence? That settles it. You should be sure to publish your breakthough and cop your nobel prizes then. *sigh*
This is why I don't argue with theists too much anymore. nikkas are so emotionally attached to "god" that they completely throw logic in the bushes.
