Ok, you're right. Nothing is hard to describe. But we do agree on the fact that we have to assume something irrational for existence to exist. By irrational I mean that it doesn't follow the causal principle.
I don't think one has to assume something "irrational" to explain existence. It can't be explained using causal relations, cause they are only applicable within existence, and not for existence itself.
(since existence includes all that exists, there is not anything out of existence, so no "outside" cause can be proposed to explain existence itself).
The question about existence is the issue of why there exist something rather then nothing. Different philosophers have tried to deal with this issue in different ways (mainly in the field of ontology) and came up with different answers.
According to some philosophers the question is meaningless. For instance any explenation of "why is it the case that A?" needs an answer in the form of "because B is the case". But in this case, such an explenation cannot be given, since we can not assume the existence of anything to give grounds for such an explenation.
The question of why there is existence is a peculiar question, and one which is unanswerable. Existence just is, it has no cause or reason.
