If there is a Creator-God, it has used methods of creation that are indistinguishable from nature, it has declined to make itself known for all of recorded history, it doesn't intervene in affairs on earth, and has made itself impossible to observe. Even if you believe in that God... why would you think it would want to be worshiped?

If for every well-intended prayer uttered in hopes of making the world a better place, there was instead a good deed accomplished, the world might look as though those prayers had been answered.

You don't want atheism shoved down your throat? OK. We will stock knocking on doors spreading our 'Truth,' and having tax-exempt organizations dedicated to atheism that have influential political action committees. We will also stop printing 'In atheism we trust' on all US currency and saying, 'One nation, under atheism" in the pledge of allegiance. We will also stop insisting that everyone who disagrees with us will be sentence to eternal damnation... Wait...

If you are religious, you believe that your religion is the 'right' one—and, in many cases, all others will be sent to hell. Similarly, a nationalist believes his or her nation is better or more advanced—and a racist believes that an inherent difference between each race make his or her ethnicity superior. All of these ideologies spawn the hate, philosophical disagreements, and prejudices that have been the catalysts for various atrocious acts throughout history.

If there's a god, it knows exactly what it would take to convince me and has refused to provide it. In fact, it has gone to great lengths to hide any evidence of its existence. That doesn't seem like a deity that wants to be worshiped to me.

Religious people claim that it's just the fundamentalists of each religion that cause problems. But there's got to be something wrong with the religion itself if those who strictly adhere to its most fundamental principles are violent bigots and sexists.

Prayer doesn’t work. Perhaps it makes the believer feel better (in the same way that meditation or deep thought would), but prayer doesn’t actually affect the external world. Not only is it ineffective, but it is also a very narcissistic practice… why would a 'God' change its 'Divine Plan' to accommodate any person’s wishes?
