database - MySQL version 5.6.23 not allowing me to create a new user/grant privileges -

It seems that I am having this problem because I was playing with drop function and drop database mysql and test. .. i think i have to reset mysql to default. What is the best way to do this? Instructions do not work for me

---- My basic question ---

I am trying to create a new user and try to give them access to my database But I'm getting a syntax error. I can not see any syntax with which I am entering. I am using MySQL version 5.6.23.

There is a screenshot of this problem:

< P> Here I have the command that is entered in MySQL:

  Allow all the authorizations on simple_cms_development. * Mypassword12345 identified 'simple_cms' @' localhost ';';  

Error 1064 (42000): There is an error in your SQL syntax;
