Dear Arved Huebler,
thank you also for your reply.
If mathematics has evolved from some empty set, at first glance it seems as if the rest of mathematics follows necessarily. The latter should be indeed true, because otherwise one couldn't trace it back to its origin - namely to the empty set. But what does this demand of necessity imply? For me, it implies that the empty set somehow contains already the whole of mathematics. But this would mean that mathematics didn't evolve, but was already hidden in the empty set. This would further mean that the empty set is not really an empty set, but could be identified with the whole of mathematics. Surely, mathematics could also have been arisen out of the blue and once it exists with its main properties (namely being a network of necessary relationships between its consituents), these relationships must be considered as necessary.
But let's prove this a bit more in detail. Think about the number Pi. In the case of mathematics having evolved out of an empty set, its value 3.14159... is not a necessity, it could well be 4.14159... or any other string of digits. Because, as outlined above, necessity implies that the whole of mathematics exists already hidden in the empty set. Surely, if the value of Pi would be different from our known value, all the other mathematical relations also had to be other than they are to guarantee the consistency of maths and/or the consistency with our physical theories. The question here is how the value of 3.14159... comes about, if there is no maths around in an empty set. If this value is logically necessary, on what basis other than on the relation between the circumference and the diameter of a circle does it 'emerge'? If true, how did this circle have been emerged from an empty set? But if the existence of circles and alike are not logically necessary, what has determined their shape and values? It cannot be mathematics itself, because from the point of view of an empty set, there is no maths around anyhwere other than potential being (of some kind). So it seems to me that in both cases, the necessity of such mathematical values or their sheer 'randomness', their has to be some kind of existence beyond mathematics which has determined such values, either intentionally and / or by necessity, or randomly. The same is valid for the existence of circles and all kinds of geometrical shapes. Randomness cannot have achieved this, because without mathematics there is no definition of randomness (in an empty set). And on what ontological properties should this 'randomness' be based, i am forced to ask (if it really does exist, what i doubt).
This leads me to the conclusion that if mathematics has somehow emerged, this could be only possible due to some entity that has more intelligence than mathematics itself. Mathematics, due to its inherent properties, cannot explain how it came about, because it cannot differentiate between a necessity and a possibility. If its existence is logically necessary, how can this be justified other than by a circular argument with the known existence of mathematics? And if it was just possible that it exists in the form we know it, what mechanism / or entity has decided which possibility to choose?

"And finally, you have criticized my argumentation regarding non-existence. Perhaps it was wrong to confuse the reader with this more philosophical stuff within this few eight pages. The idea was to define the initial starting point of mathematics. It can be the existence itself, which is unfolded to the infinite complex structure of mathematics. But if you assume non-existence as first entity ever, in the same moment existence is logically included as a second entity. For the main hypotheses, this question seems not crucial."
I agree, as far as the natural numbers are concerned. But for all other features of mathematics, i would pose the questions i wrote above. Anyways, thank you very much for your detailed reply and good luck in the contest!
Best wishes,
