Religious people believe in the miraculous.
Atheist me finds a different sort of miracle embedded in religiosity: the fact that almost everyone who embraces a particular religion is highly confident, if not absolutely certain, that their particular faith is The True One.
Christians, Muslims, Jews, Hindus, Sikhs, and followers of many other creeds (including the Eastern mystical/spiritual teaching I followed for many years, Sant Mat) -- with just a few exceptions each devotee considers that somehow they've been fortunate enough to find the truth about an ultimate divine reality, while billions of people who believe otherwise are sadly deluded.
This makes possible the atheist saying:
“I contend that we are both atheists. I just believe in one fewer god than you do. When you understand why you dismiss all the other possible gods, you will understand why I dismiss yours.”
Now, religiously-minded people might point out that in science alternative theories may compete with each other. True enough. But there are ways to determine which scientific theory is most correct.
Such doesn't exist in religion, or we wouldn't have thousands of faiths (Wikipedia says about 4,200) competing with each other for thousands of years with no demonstrable evidence of which, if any, speak the truth most truly.
-- What if you, believer, are right about there being a God but picked the wrong one?
-- What if you're right about God but picked the wrong religion to worship Him, as Muslims, Jews, and Christians mutually claim about each other?
-- What if you're right about God and your religion but wrong about which denomination, sect, or church has it right?
-- What if no demomination or person has figured it out correctly yet?
-- Can you, in your little corner of faith, in your tiny denominational box, shaded by your own personal perception, interests, likes, and dislikes, really be so sure that all of these billions of others have it wrong and that you have it right?
-- What if you are wrong about God's existence?
-- What, then, are you doing with some or much of your life?
-- How much time and effort are you wasting chasing fairy tales out of a book that is ancient literature turned social-control manual?
-- What are you doing to yourself, to your psychological well-being, when you must constantly lie to yourself about your worldview, which does not match your view of the world anywhere you look without relying on rationalizations and contortions of facts?
-- What are you ignoring or failing to learn about the world or yourself because you think you already have answers or because you want them less than your cherished beliefs?
-- What are you doing when you support inhuman social policies, hold back education, suppress healthy expressions of sexuality, oppose beneficial measures in regards to sexual health, deny others their basic human rights, curse the names and lives of your enemies or go to war with them, vote for idiotic politicians because you like their beliefs, held without evidence, enough to act without regard of their backwards ideas on key matters of policy?
-- What are you asking from those of your friends, your family, and your community who do not believe and yet are currently all but forced to listen to and to pretend to respect your religious beliefs, delusional rambling, misplaced thanksgiving, and unflattering solipsism?
-- What actions and thoughts do you deny or attempt to deny yourself on the grounds of your faith, activities and mindsets that might bring enjoyment, pleasure, meaning, or fulfillment to your life?
-- Which of those do you do anyway, needlessly hating yourself for it even while you do it?
-- What do you do only because you hope for bonus points with your imagined creator, selfishly trying to improve the chances that you will get your reward?
