How could anything make sense which is based on something you think it doesn't make sense?

That's not always true. Some people are so thankful when they hear that other people prayed for them. In my experience, these tend to be very religious people, but it touches them that so many people thought of them in their time of need, and it makes them feel better. Usually this is for someone who's sick and in the hospital, or something that's harder for people to actually help out with. (Yes, people can donate money to a sick person rather than pray. But my point is just that some people do appreciate prayers, and it does help them; at least mentally.)

has god ever let anyone down here? then why bother serving a god that constantly fails his people.

Well, usually the poor countries are more religious than wealthy countries. It gives people hope, which in turn makes it easier for the governments to suppress their people. Faith/hope < Actions

Still, I fail to see how that is relevant to this topic.

let's all go to a field and drink cyanide

i guess religion is the greatest evil known to man.

yes it is begging

we pray to god and god doesn't do schmickle

Not from my experience, at least. (which includes the former me, my family and relatives)

To this day, I only hear my family pray for people at hospital and/or similar situations. And also my dad (who drive the car) always pray for us to have no car accidents on long trips.
