People
can tell us they they are praying or have prayed. This doesn't mean that they do. I am pretty confident that there are people that pray that don't share the fact that they pray. Does that mean, in your view, that they don't pray?
@JustGeorge already pointed out some other purposes for prayer than what you appear to be familiar with when she said...
There are those that pray for the purpose of devotion, love, and connection to the divine. As
@JustGeorge said, prayer isn't always about getting stuff and it's not always about getting some supreme being to affect change.
