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.

While it may be impossible to 'disprove' the existence of some 'Higher Power' or abstract Creator, it is entirely possible — through analysis and research — to find discrepancies within the ancient, organized religious traditions that support the idea of a specific God.

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.

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?

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?

Not only do I believe that it is possible to maintain moral standards without the crutch of religion but I would argue that it is the only way to achieve true goodness.

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.
