What do you think of this question? Initially, one of the issues was excessive capitalization, but do you think that it's appropriate otherwise? I can see what the author is asking, but one could argue that it's not a well-worded/well-conveyed question, so I was wondering what the policy on this would be.
Whether mathematical concepts are based on anything solid is a perennial question. The questions and even some of the standard answers often include variations of the "based on lies" idea (e.g., strict formalism) and I think the OP should not have been pressured to change the wording. He gave his honest and sufficiently humble impression of the situation, and stronger words have been used (less humbly) by great mathematicians to describe the same apprehensions. Many people stop studying mathematics or lose interest in it due to similar worries about the unreality of the subject. If there are, in fact, simple convincing answers to the question it would not hurt to see them posted.
Anyway, this is another completely reasonable question voted down en masse just for being unconventionally or provocatively expressed. I upvoted as did Matt E but the downvotes presently overwhelm this, 10-to-2. If Bishop Berkeley's criticisms of the mathematics of his time were posed in a math.SE-equivalent environment they would have been downvoted and quickly closed. It would be good to develop a more tolerant site culture instead of making new case by case arguments each time from the "left wing" to (not always successfully) protect endangered questions.
I didn't see the original many-caps version of the question, so this answer applies to the question as currently written.
I don't think it is a terrible question. The OP is asking basic questions about the meaning of mathematical concepts. The OP's comments about God suggest an (at least implicit) anti-idealist point-of-view, which means that the Platonistic view-point that satisfies e.g. me regarding the subjects of the OP's question is probably not satisfactory to the OP.
If there were a separate philosophy of mathematics SE site, then this question would belong there, but since there's not, I think it is quite appropriate here.
I also disagree with the implicit suggestion by various commenters that the OP simply doesn't understand the concepts being discussed. As the OP wrote, they are are a programmer, and (most likely) have a good technical facility with mathematics. The OP's concern is philosophical and (in my view) far from frivolous.
