Problem with Laravel's migrate?

I just installed Laravel on my pc to learn a little bit. But I'm having a little problem using migrate . Whenever I try to use migrate , it has the following error:

  

[Illuminate \ Database \ QueryException]
        SQLSTATE [42S01]: Base table or view already exists: 1050 Table 'clients' already exists (SQL: create table clients ( id int unsigned not null auto_increment primary key, name varchar (255) not null, responsible varchar (255) not null, email text not null, phone text not null l, address timestamp null, obs timestamp null) default character set utf8mb4 collate utf8mb4_unicode_ ci)

It does not generate the new created_at I created, but when I change the date from a updated_at to an earlier date, it works.
