If we removed all the trappings that accompany God, would he/she still exist?

If everyone were to wake up tomorrow realizing that there's no heaven or hell, would they behave worse or better? Imagine how many institutions that thought would bring down. You wouldn't be able to pay or fast for your seat in the pleasant afterlife cause nobody knows what that would be like. It would be chaos, I think. There will be people who won't be able to cash in on other's fears of God's retributions. Imagine, having to start living your life doing some real work.

If God does exist, he must feel terribly used and abused.

P.S. I'd like a gender-less God, wouldn't you? Enough with the he/she/it nonsense!
