Life requires some level of faith in the inner workings of the world. Proof is not always available to support belief but I think that it is reasonable to accept as probable that the sun will rise each day.
I have been on earth for 22,456 sunrises but I find it difficult to remember one as good as this one.
I know it is idle to wonder how long I’ll live but on the basis of indirect evidence I have faith that I will be here tomorrow and therefore tomorrow’s sunrise could well be the best one I ever see.
As for the rest of my future life I am sincere when I say that I believe it to be more than a vague likelihood that I will see another 5000+ sunrises.
