In support of what? Virtual particles are not nothing.

Who say's that they were (or, are)???  Point is that fields create energy and energy creates fields and fields create particles and particles create fields.  Consider this:  You're sitting in a lab and on your lab table is a test charge; you measure the magnetic field and get nothing, no magnetic, only an electric field.  I come running through your lab, and while passing your test charge, I measure a magnetic field.  Which gives???  You see no magnetic field, whereas, I do see a magnetic field.  Is one of us right and the other wrong?  How could there be a magnetic field present for one of us and not the other?  Well, it's just the way Nature works!

Back to the Universe -- it created itself, it is its own cause; it's a "necessary entity" -- it came from nothing, by nothing, of its own accord; perhaps "abstract objects," such as numbers created it; who knows?  We may never know; to say that "God did it" is just an endless variation on the "god of the gaps" argument.
