Problem with "Route" resource in laravel 8 - laravel

Question

My app was working fine until I wanted to replace my "get" routes with a single "resource" to be able to include a delete function. I remind you that I am a beginner in laravel so it is surely due to the fact that I can not be able to make a "resource" route.
This is my code :
Route::get('/', function(){
return view('front.pages.homepage');
})->name('homepage');
Route::get('/garages', [GarageController::class, 'index'])->name('garage.index');
Route::get('/garages/{garage}', [GarageController::class, 'show'])->name('garage.show');
Route::get('/garages_create', [GarageController::class, 'create'])->name('garage.create');
Route::post('/garages_create', [GarageController::class, 'garage_create'])->name('garage_create');
Route::resource('cars', [CarController::class]);
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Models\Car;
use App\Models\Garage;
class CarController extends Controller
{
public function index()
{
$list = Car::paginate(10);
return view('cars', [
'list' => $list
]);
}
public function store()
{
$garages = Garage::orderBy('name')->get();
return view('carCreate/carCreate', [
'garages' => $garages,
]);
}
public function create(Request $request)
{
{
$request->validate([
'name' => 'required',
'release_year' => 'required',
'garage_id' => 'required', 'exists:garage_id'
]);
$car = new Car();
$car->name = $request->name;
$car->release_year = $request->release_year;
$car->garage_id = $request->garage_id;
$car->save();
return redirect('/cars');
}
}
public function show(Car $car)
{
return view('carShow/carShow', compact('car'));
}
public function edit($id)
{
//
}
public function update(Request $request, $id)
{
//
}
public function destroy($id)
{
//
}
}
And my error is : ErrorException
Array to string conversion
