It could be they got them in an e-mail or read them off of a message board for all we know.Then you do not know that it could be through prayer.
The Bible does not tell us how the prayers got there.
It does not give examples of people praying to angels or to dead people anywhere and in fact, tells us not to do those things.
Therefore, to assume that the prayers got there by having angels and "Saints" listening to them having been prayed to them rather than to God to pass them on to God is stretching things a bit.
Perhaps they hear the prayers that we pray to God?
I really have no idea.
But the Bible does not tell us so we don't know.
And there is nowhere in the Bible apparantly where anyone is shown praying to an angel or to a "Saint", nor where anyone is told to do so it seems.
