I don't spend all my all my time watching atheist videos on youtube. Sometimes I watch general ones as well (and ofcourse I don't spend all my time on youtube full stop) One cool video is this one called the virtual barber shop. Basically you put your headphones on (you have to do this for it to work as it won't have the full effect with normal speakers) and shut your eyes. Basically it makes it feel like there is a man actually in the room with you. You've properly seen those 3d cinemas, well this does the same but with sound. Anyway, make sure you watch it.
Then it occured to me that it is very easy to trick the brain. The virtual barber thing makes it feel like a man is in the room with ou but there isn't one. Maybe when xians talk about religious experience it is something very similar. They think they can feel Jesus but is is an illusion of the brain.
