Was it necessary to create anything?

Smaug, if you keep that complex stuff up, you may end up where you currently do not want to go.

Been there, done that.

Speaking seriously, I don't completely reject the idea that the Universe may have been created (by chance, during an experiment or in an infinite variety of other scenarios) because the question itself could not be answered in the most general sence (i.e. "Does the Universe have a creator?"). People who like to discuss such issues often rush to give out answers (mostly due to their ignorance) and forget that before trying to find an answer to a question it is necessary to deduce if it is principally possible to answer the question or not. In this case trying to find an answer in the most general case has no sence since the question could not be answered (for now).

However, more particular formulations of this question can be answered. And the answer is negative. Abrahamic religions fall in this category (among others). I.e. - no Yahweh & CO. Apologetics are usless here because there are only two basic scenarios of apologetic reasoning: the reasoning is proven outright wrong or it leads so far from the dogma that it basically discredits the religion itself in process (in this case it also eventually gets stuck in fallacies but on a higher level). Deism is somewhat on the fence due to being too vague to define and discuss. What some Christians fail to understand is that a "potential Creator" that is implied by the more general formulations of the Creator Question has nothing to do with Yahweh/Jesus or almost any other god or goddess created by humans. The answer may very well be "42", you know.

Some theists do not understand why we atheists pay so much attention to religion. The answer is quite obvious. We do so because there are a lot of believers around and it's necessary to understand and their dogma to analyze their actions. Religion is not only a provider of personal philosophical concepts but also a very powerful instrument of control and has to be understood with full clarity, including it's philosophical basis.
