Do you think this is a valid summary of mankind's need to worship?
Personally, I'm leaning towards believing that mankind does not need to worship. Instead, I think mankind has a strong inclination to follow tradition. Hell, mankind may even have a "need" to follow tradition. Traditionally, mankind "needs" to worship. 
Plainly put, I think mankind should spend a few years not worshiping; y'know, see how it goes. I'm sure doing fine, and god seems to be ok too. Maybe throw out the occasional prayer for the less fortunate, just to keep the ole heart in line.ps. can I share with you a fascinating book titled "Mankinds Search for God"? 
When you lie out under the stars, do you sense the divine?
I used to, of course. Now I don't. "more like sense the mysteriousness and vastness of the universe. But divinity? Nope." ditto. Also the connectedness.ps. Elsewhere, I like the way you connect atheism with spirituality; fascinating. Keep it up if you ever want to get laid by anyone who isn't an atheist, lol.
