Who was Shakespeare

I Google searched "who was Shakespeare" and found a link to Pbs. There i found out that he was born in the year 1564, at the age of 18 he married Anne Hathaway, they had kids and moved to London where he became a successful actor, poet, and a playwright. The mystery about him is that people believe that other people, more highly educated, wrote his plays one of them being Edward De Vere from the article we read for homework. i know when i hear the name Shakespeare  my mind is filled with a ridiculously smart and successful man. I never knew that his identity was being challenged and that he might of never written any of his famous plays.
