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?

We are all born free from all religious affiliations and only come to believe in such things after being introduced to it ― so, atheism is the default position. Although some children are not indoctrinated with a specific religion before the age of reason, there are many more who are.

Believers often forget that most atheists used to be religious, that many non-believers used to think they had a personal relationship with their God and they used to 'feel' the power of prayer. They've since learned that it was all a farce, that their feelings were internal emotions and not some external force.

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?

It is my sincere opinion that our precious time on earth should not be spent attempting to justify unbelievable acts of cruelty, death, and disease as a part of 'God’s Plan' or the greater good — and clinging to ancient texts that preach ill-concealed bigotry and sexism. Instead, we should find ways to make this life happy and satisfying, without regard to the unknowable nature of an afterlife.

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.

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.
