Save form data to the database

I'm having a hard time trying to create a form in Laravel 5.4 . The form appears normal, but when I click the button, the page reloads and the data is not saved in the database!

{{ Form::open(array('url' => 'users')) }}
<div class="form-group">
    {{ Form::label('name', 'Name') }}
    {{ Form::text('name', null, array('class' => 'form-control')) }}
</div>

<div class="form-group">
    {{ Form::label('email', 'Email') }}
    {{ Form::email('email', null, array('class' => 'form-control')) }}
</div>

<div class="form-group">
    {{ Form::label('password', 'Senha') }}
    {{ Form::password('password', array('class' => 'form-control')) }}
</div>

<div class="form-group">
    {{ Form::label('nerd_level', 'User Level') }}
    {{ Form::select('nerd_level', array('0' => 'Nomal', '1' => 'Admin'), null, array('class' => 'form-control')) }}
</div>

{{ Form::submit('Create the User!', array('class' => 'btn btn-primary')) }{{ Form::close() }}

Controllers :

<?php namespace App\Http\Controllers;
 use Illuminate\Http\Request;
 use Illuminate\Routing\Controller as BaseController;
 use App\User;     
 use Illuminate\Support\Facades\Input;
 use Illuminate\Support\Facades\Validator;
 use Session;
 use Illuminate\Support\Facades\Redirect;
 class UserController extends BaseController
 {
public function index()
{
    // get all the users
    $users = User::all();

    // load the view and pass the users
    return view('users.index')
        ->with('users', $users);
}
public function create()
{
    // load the create form (app/views/users/create.blade.php)
    return view('users.create');
}
public function store()
{
    // validate
    // read more on validation at http://laravel.com/docs/validation
    $rules = array(
        'name'       => 'required',
        'email'      => 'required|email',
        'password'   => 'required|min:6|confirmed',
    );
    $validator = Validator::make(Input::all(), $rules);
    // process the login
    if ($validator->fails()) {
        return Redirect::to('users/create')
            ->withErrors($validator)
            ->withInput(Input::except('password'));
    } else {
        // store
        $user = new User;
        $user->name       =  Input::get('name');
        $user->email      = Input::get('email');
        $user->password   = bcrypt('password');
        $user->save();
        // redirect
        Session::flash('message', 'Usuario cadastrado com sucesso!');
        return Redirect::to('users');
    }
  }
 }

Routes :

Route::get('/', function () {
return view('welcome');
});

Auth::routes();

Route::get('/home', 'HomeController@index');


Route::group(['middleware' => ['auth', 'auth.admin']], function () {
  // Minhas rotas da administração aqui
Route::resource('users', 'UserController');
Route::get('/admin', 'AdminController@index');
});

Could anyone help me?
