The generally accepted specific formulation of the "Something Rather Than Nothing" issue in philosophic studies came from Martin Heidegger, but has been so widely used.. even to book titles, that it is almost a universal topic now.

A.N. Whitehead said early in "Process & Reality"... "everything must be somewhere" and went on to assume (in a MOST convoluted way) that 'something' must have always been... ummm.. here.

Too bad those guys didn't have Greg F. to clarify it all and save them all that thinking. (there sure are relevant aspects of religion when the Texas school board meets.)
