laravel - dependency mismatched for composer and php

one text

when creating laravel projects using composer the required dependency of php is 8.0 which is not installed in my kali linux machine, i have greater version of php as php8.1. so dependency mismatched. composer not installing any packages.

I have also php 7.4 but not php8.0. I am not understanding why composer creating projects with php8.0 which is not installed.

Here is composer.json file
