You can't know something if you are uncertain. Certainty requires faith. Faith is often given because something has been presented with enough evidence/proof for the person to believe it.
If one believes something, but is not certain... then they don't know it, even though they think it quite possible. Certainty is then the amount of faith one requires in the truth of a thing before they can know it. Ultimately: certainty of a thing is knowledge of a thing. I am certain that I am sitting in my chair in front of my computer stressing out about fucking up my computer... I know all of this. I am uncertain which stars are where in relation to the earth... i do not know this.

Please give me a home where cloud buffalo roam
Where the dear and the strangers can play
Where sometimes is heard a discouraging word
But the skies are not stormy all day
