Religion, the hub of belief is descovered to be of alternative origins from which it supposedly began and thus is not 'true'. Science gets 'updated', it has flaws (gaps) that are 'covered' over by 'theories' and not then true indeed. The Universe itself is the 'Great unknown'. Every fact about it is just theories an insignificant race on an insignificant world in an insignificant galaxy has devised to try and understand it. Isnt it strange that any so called certanty is subject to be questioned? Logic is not universal as many things that defy logical principles seem to exist, so itself is not a rule. Words have no fact in them that can be drawn apon as truth to an existance or proper meaning; Psykic-is it actually true to exist as the definition proclaims: telekanesis, extra terrestorals, Reserection, omnipresence, God, Reincarnation. So if a word has a meaning it also is subject to change.
Facts are often just the majority opinion. History, science religion ect.Such as the origin of the pyrimids, or the purpose of stone henge.
Therefore; Belief=fact. truth=myth.
