Ben,

Do you think that the 10^10^100th digit of Pi has a certain value even though we can never know what it is and no one has ever or will ever (in this universe at least) be conscious of it? If I assert the digit happens to be 8, would you agree that my assertion must be either true or false? If so, where does this truth exist?

Note that one cannot say it has an indefinite or value, or that its value is inconsequential because that level of precision will never make a difference in any equation we work with. Euler's identity: e^(Pi * i) + 1 = 0, would be false without each of the infinite digits of Pi having a definite and certain value. These values that are unknown to use, but nonetheless must be there.

Mathematical existence isn't a matter of being "there", it's a matter of satisfying, making true, a certain proposition. So why does the putative digit of pi have the value it does, because it satisfies certain propositions which we infer from other propositions we are pleased to hold hypothetically true as axioms. Existence in the usual sense never enters into it.
