there is always belief... belief in anything out of the ordinary... not all great scientists believe there is a god... so, if i don't believe in anything out of the ordinary is beiing premature? i don't know. i just don't believe anything i can't see or being proven scientifically.....
anyway, this is off-topic..
going back, i don't think there's any difference with that as you are worshiping a person higher than us...
in an observation, prayers are usually and mostly done alone... worships are done in a group... well, literally, at least..
to see is to believe jud... did science catch up with God lately?
