Atheists pray? Well, with religious naturalism, maybe they do!
They make jokes about prayer.
At my house, the obligatory childish Catholic “bless us oh Lord for the gifts we about to receive” has been replaced with nice words thanking my wife for making a great meal and to feeling fortunate to be all together for a holiday. Not really a prayer but an acknowledgement of our need for each other and our gratitude for being here for another Thanksgiving.
How about you cook a turkey this year? It is pretty fun.y wife finds it to be a very profound expression of thankfulness to her. 
oh no, that will completely destroy the family. The ramifications will be felt for decades to come. 
I will offer a prayer when I think is is appropriate to do so. For example, at a funeral I might offer a prayer out of respect for the beliefs of the deceased. It’s not my beliefs that matter in that setting. I can’t speak for all atheists, but I’ve offered that comment in the community where I moderate, and not gotten any objection.
The efficacy of agnostic prayer is not a topic I will attempt to address today. 
I don’t equate saying kind words or eulogizing a deceased friend or loved one a prayer.
Neither do I. What I mean is a offering a thought for God, mustering whatever level of belief is available to this agnostic. I do not expect any result from this, other than a quiet moment of meditation (often made difficult by someone droning on at the front of the room), but again - I’m not doing it for myself.
I honestly try. Not often, but when I do I try to do so sincerely. If anyone wishes to say I’m doing a crappy job of praying then I accept the criticism. I have no evidence either way, so I go with my feeling on the matter.
I see nothing wrong in an “appeal to the gods” once in a while. Usually out of frustration. But then logic, and reason kick in and I assess the situation that I find myself in. I certainly don’t like the situation but I use reasoning and human empathy to do the right thing.
Thank God for reason and logic!!!
Yes, and I thank the Sun for the sunshine, (and an occasional skin cancer).
Sometimes I tell people I’m agnostic because I can’t be bothered to learn new swear-words.
