If you are a Christian you would not call dead people dead. Saints are in heaven; they have seen God. The bible tells us that the kingdom of heaven inside of us, in our Christian hearts, that God abides in us, and where God is His saints are too.
There is no reason whatsoever why we cannot ask the saints to pray for us. No one is forcing you to do so, but if it is "logic" that drives your statements, there is nothing logical about the faith. In fact, to non-believers it appears rather silly and imagianry.
You are changing the subject and challenging my faith rather than even discussing the issue. NO WHERE in the bible does anyone bow his head or otherwise and ask a dead person, and we know who they are, to pray for them.
