"Their" existence ? Mathematical statements needs "chatty" machines.
Mathematical truth, a priori doesn't (although "free structures" can
feature some chatty aspects many times).
Let us make the following convention. When I will say "I believe there
exist a perfect number", it is a shorter expression for, I believe the
proposition "There is a perfect number" is true (satisfied in (N,+,*))
independently of me, or of any theory of cognition. (A good thing,
giving that a theory of cognition is build *from* digital machine, that
is from number theoretical relations).
