A big rumour or theory circulating the ‘net is that a page in Before Watchmen: Dr. Manhattan #4 “reveals” that Dr. Manhattan created the DC Comics New 52 or the DC Comics Rebirth’d Earth. Dr. Manhattan creates the new DC Universe 4 years before the 2016 DC Rebirth event!
(2011) Before Watchmen: Dr Manhattan #4 displays this in glorious blue panels on the interior pages
(2016) end of DC Universe: Rebirth #1
(1986) Watchmen #12: between Dr. Manhattan and Ozymandias.
