Eliezer, I really liked your prayer.
The obviously religious ones like Abigail and Richard aren't really worth responding to except with general disdain.
To the ones complaining atheism is religious, if you want to see religous atheism read "In Defense of Secular Humanism" by Paul Kurtz, especially "Secular Humanist Manifesto". I had read it because I liked Kurtz's skeptical stuff, but it was awful. The Manifesto writers basically just changed their faith from God to faith in the Government. I have seen similar things since, mainly from academics.
The argument about probability 1 and so forth - I use the words certain and impossible regularly to mean the likelihood of something not being true or of being true to be so low as not being worth consideration. I will repeat what I've said before, putting arbitrary (spurious) numbers to likelihoods is more likely to result in contradictions than not.
At tonight's Thanksgiving, Erin remarked on how this was her first real Thanksgiving dinner away from her family, and that it was an odd feeling to just sit down and eat without any prayer beforehand. (Yes, she's a solid atheist in no danger whatsoever, thank you for asking.)
And as she said this, it reminded me of how wrong it is to give gratitude to God for blessings that actually come from our fellow human beings putting in a great deal of work.
So I at once put my hands together and said,
"Dear Global Economy, we thank thee for thy economies of scale, thy professional specialization, and thy international networks of trade under Ricardo's Law of Comparative Advantage, without which we would all starve to death while trying to assemble the ingredients for such a dinner as this. Amen."
