They exist if there is a consistent description of them. Even within
conventional physics there is room for that, as discussed recently
on this list. In the MWI or in eternal inflation models, everything
that is not strictly forbidden by the conservation laws will happen.
Flying pink elephants can e.g. exist on planets with an extemely
dense atmosphere, there was a NGC documentary a few years ago about
this topic, it was suggested that you could have flying whales on
such planets.
I was taking about the flying pink elephants on our planet. If you
question was "does they exist in general", then, as any physical
object is the result of stable pattern supervening on infinities of
computation, we can just say "we don't know, probably in some rare
branches of the comp-quantum multiverse".

Yes, at least for the chap that holds the belief and the belief
is true (ala Bruno).
Right, but like I said, I believe also that flying pink elephant
are not pink. And so I can easily prove that flying pink elephant
does not exist, as far as I am consistent.

A fictionalist account holds that some things are fictional, i.e.
don't exist even though their complete description is self-
consistent. Everythingists apparently reject this idea.
Platonists seem to equate 'true' with 'exists'. If you believe
17 is prime you must believe 17 exists. I think this is wrong.
If you believe that a flying pink elephant is pink, must you
believe a flying pink elephant exists?
