I think all religions are just different perspectives on the same spiritual ideas, and that people get too caught up in the metaphors. That religions are just tools you can utilize at your own digression to live a better life and not blueprints to militaristically follow.
There's this thing Karma Yoga which is basically doing everything in your day as a devotion to Krishna. So you'll be washing the dishes and keep the idea "I'm washing the dishes as an offering to Krishna" in your mind, and you're meant to remove the idea of self from the equation and just do them for him. But it doesn't matter that you're doing it for him, it's just an exercise to make you more concious and aware, allows you to disengage from the ego and be aware that the you is separate from your body and thoughts etc. But some people miss the point and see it as "EVERYTHING I DO SHALL BE IN SERVICE TO YOU GREAT KRISHNA. LOOK HOW MUCH FAITH I HAVE AND HOW MUCH I'M SACRIFICING TO PLEASE YOU!!!"
So I think the Christian concept of praying to god is just an exercise in gratitude, positive think, visualization, etc and if there is some form of god, or even if there's not, he doesn't give a shit if you pray to him or not, and he doesn't punish you or reward you if you do/don't pray for him. You do that to yourself with the things you gain from doing this exercise (or not doing it). But there's obviously ways that you can practice those exercises as well without praying to god (gratitude journal, habits, etc).
So I think religions are just toolboxes, and people just have to find the best toolbox for them. Or even better look at all the toolboxes and pick which tools they like the most. Atheism is one of those tool boxes too fwiw (I'd assume it'd be completely distilled ideas from a logical/scientific perspective).
Sometimes I do Karma Yoga and provide offerings to Krishna. I don't believe in it one bit, but I believe in why I'm doing it and the effects it has on me. I could gain these effects in more normal ways than becoming a servant to a magical man in the sky, but I like the framework it provides - and I enjoy it. On some level too I probably trick myself into believing it's way more spiritual than it is, which is fine, more gains for me
I also agree with Acombfosho (not trollin you this time man!)...
I am agnostic too, because the finite mind cannot comprehend the infinite. Saying there is or isn't a God is basically saying you know everything about the universe.
Debating about gods and their actions/existence in a literal sense seems pretty frivolous. I also think people take religion way too seriously. This is just a ride.
