There needs to be more than blind belief something is so in order to consider it a matter of fact. That is not a reliable way to form an understanding of what is or is not so, of how the world and the Universe is actually ordered.
What you're describing is the way people throughout the Medieval period came to believe that the Earth was at the centre of creation. No doubt they had absolute unshakeable belief and faith that it was how the heavens were ordered.
How you describe what we do maybe different but we are doing the same thing. It is when we believe we know we start acting on our beliefs we start walking in faith. You can have faith in many different things and people it is our confidence our faith in them.
