(330) Are we really to believe that Shakespeare plagiarized?

The snobbish Shakespeare (or Stratfordian) Academe 
never even began to try 
 to solve any of the countless inconsistencies!

Are we really to believe, that the same  literary idiomatic metaphor was used in London by 3 different poets,  Marlowe, Shakespeare and Heywood , within a few years?  ---  Is this plausible?

    "Doktor Faustus"                 (Marlowe):
         »Was this the face that launched a thousand ships/
         And burnt the topless towers of Ilium?«
   " Troilus und Cressida"     (Shakespeare):
         »Why, she is a pearl,/
          Whose price thath launch’d above a thousand ships,/
          And turn’d crown’d kings to merchants.« 
    "The Iron Age"                   (Heywood) 
          …..this is the beauty,
         »That launch’s a Thousand ships from Aulis gulfe 

Conclusion : Academic Shakespeare experts obviously never hesitated to accuse Shakespeare and Heywood of strange plagiarisms...

This would not have been necessary, if they had taken into consideration  the possibility of an existing Shakespeare Marlowe Authorship Theory that can solve these inconsistencies.
