The interest I have in believing in something is not a proof that the something exists. - Jerry Coyne

But none of this criticism of science makes religion even a tiny bit more credible...
In contrast, religion has never been right in its claims about the universe—at least not in a way that all rational people can accept. There is no reliable method to show that the Trinity exists, that God is loving and all-powerful, that we’ll meet our dead relatives in the afterlife, or that Brahma created the universe from a golden egg. Lacking a way to show its tenets are wrong, religion cannot show them to be right, even provisionally.

Theodicy is the Achilles Heel of faith. There is no reasonable answer to the problem of gratuitous evil (i.e., the slaughter of children or mass killings by natural phenomena like tsunamis), and the will to continue believing in the face of such things truly shows the folly of faith. For those evils prove absolutely either that God is not benevolent and omnipotent, or that there is no god. (Special pleading like “we don’t know God’s mind” doesn’t wash, for the same people who say such things also claim to know that God is benevolent and omnipotent). Both nonbelief or belief in a malicious or uncaring God are unacceptable to the goddy. Ergo, any rational person who contemplates gratuitous evil must become an agnostic, an atheist, or someone who rejects the Abrahamic God. It is a touchstone of rationality.

Putting all this together, we see that religion is like Sagan’s invisible dragon. The missing evidence for any god is simply too glaring, and the special pleading too unconvincing, to make its existence anything more than a logical possibility. It’s reasonable to conclude, provisionally but confidently, that the absence of evidence for God is indeed evidence for his absence.
