There are a number of reasons why it is unlikely that Bacon wrote Shakespeare's plays. First, there is no direct evidence to support the claim. There is no known correspondence between Bacon and Shakespeare, and there is no evidence that Bacon ever expressed an interest in writing plays. Second, the styles of writing are different. Shakespeare's plays are written in a poetic, lyrical style, while Bacon's works are written in a more formal, philosophical style. Third, the themes and ideas in Shakespeare's plays are different from those in Bacon's works. Shakespeare's plays often explore themes of love, loss, and betrayal, while Bacon's works focus on topics such as politics, science, and philosophy.
In addition to the reasons listed above, there is also the fact that Shakespeare was a successful actor and playwright during his lifetime. He was well-known and respected by his peers, and there is no evidence to suggest that he was not the true author of his plays.
The theory of Baconian authorship is based on a number of circumstantial evidence and speculative reasoning. There is no direct evidence to support the claim, and it is not supported by the majority of scholars and historians.
