I think believing in things which there is proof of makes more sense than believing in things there is no proof of. I don't think that's a contradiction. By believing in things with no proof our whole justice system collapses.
I appreciate conversely there is no proof that gods and ghosts and goblins don't exist, but this is the reality of our world. Proof + physics = stuff that exists. That probably sounds narrow minded to all the father christmas worshippers, but the fact is, your parents lied to you from a young age and you bought it.
of course believing in things for which there is proof makes a ton of sense.
like there is proof that there is so much we don't know.
that unknown information counts, it goes to defining what reality actually is.
to ONLY believe in that which there is proof for, knowingly omits those things which are real but not yet provable.
if this was 1491 you'd believe the world was flat and you'd tell round worlders they believe in fairy tales. then the next year, you pronounce yourself a round worlder.
it might be prudent to go about daily life as if it were flat, but you still would have been wrong.
one can conclude the world ends at the horizon and they can get along just fine like that. but they'd be wrong.
you think you know but YOU just accept what is told to you.
the world is flat until it isn't, the earth is the center of the universe until it isn't, the sun revolves around the earth until it doesn't....... YOU wait to be informed of what YOU think.
