The question 'why is there something and not nothing?' is not mere metaphysical speculation but a response to the ontological condition of thins, a hidden lack or absence which is the enabling condition of there being anything at all. So you could say that the question itself is its own answer in a profound way. It is no coincidence that the same 'logic' applies to experiencing, or consciousness - it only arises because of a hidden absence within itself - that which gives it an ineradicable direction or intent - misnamed as will.
