I made a game where blocks fall and you have to dodge it but can't get the hitboxes right - python-3.x

Question

The hitbox seems to be on the left side of the cube, so it feels like the game is ending without me even hitting anything. I want to make it that the hitbox is exactly on the red rectangle, so that it's obvious that the black rectangle had hit you.
the up and down controls are just for future movement option if needed.
here's the code
import pygame as pg,pygame
import random
import sys
pygame.init()
WIDTH = 1000
HEIGHT = 800
# Positions, sizes
SPEED = 10
MIDDLE = [500, 400]
score = 0
player_size = 90
player_pos = [WIDTH/2, HEIGHT-2*player_size]
playerX_move = 0
playerY_move = 0
enemy_size = 50
enemy_pos = [random.randint(0,WIDTH - enemy_size), 30]
enemy_list = [enemy_pos]
# Colors

Answer 1

I would recommend using a list of pygame.Rects instead of a List with the positions of your enemies. This would also allow you to use pygame.Rect.colliderect() instead of your detect_collision function.
I've also linked the Pygame Docs.
