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.

Without cultural indoctrination, all of us would be atheists. Or, more specifically, while many may dream up their own gods as did our ancestors, they would certainly not be ‘Christian’ or ‘Jewish’ or ‘Muslim’ or any other established religion. That’s because, without the texts and churches and familial instruction, there are no independent evidences that any specific religion is true. Outside of the Bible, how would one hear of Jesus? The same goes for every established religion.

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?

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.

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.

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.
