Physical-atom-based empirical evidence is limited to what early Heidegger discussed in his "Being and Time"--and the (unfinished) answer is: "no thing is forever" (512 pages).
"Belief" is "be-love" (from PIE *leubh-", "to care, to love"; middle transition term OE "bileave," "confidence, faith in a religion"). So, whatever you cherish, there is your caring, your love.
This is all with ontology: I Am, I love, I believe, in an epistemological something: God, an atom-based tree, etc. At this level of complexity, Godel's Incompleteness work shows that in any given "belief system" there are unanswerable beliefs (truth-claims, etc.). Hence, human awareness is necessarily incomplete. The level which permits absolute surety is in this ballpark: "Jesus answered and said to them, 'Even if I am bearing witness concerning Myself, My testimony is true, because I know from where I came and where I am going. But you do not know from where I come or where I am going.'" (John 8:14) This is part of the opportunity to draw nigh to God by letting this Mind abide, aka living Life for Christ's, Truth's, sake, by putting off the old "loves of the world" (as "first love"): it's called "self-transcendence" and "faith." Much may be known, but absolute certitude is not something simply of this world.
