Maybe you just don't have the technology to be able to discover it.
Like radio waves to the caveman. Like the existence of 10s of billions
of galaxies that were only a smear on a lens prior to Hubble.
And try asking it the other way around. If something does not exist,
can you prove it does not exist? That's harder. Can you prove there
are not 4-dimensional creatures who can see simultaneously both the
insides and outsides of your body as normal - like Francis Bacon [the
modern one] ugly paintings.

Yes, Gödel has you by the scruff of the neck.
