Script giving points to only Player1 on the leaderboard?

I wrote a script that basically worked so that every time a player clicked on a specific part, it would give them one point. The part would change color, and there would be a 3 second cool down. However, when I tried testing it with 3 players, the points were only being assigned to Player1, regardless whether it was Player2 or Player3 that actually clicked the part. Here is the code I have below:

--leaderboard script
game.Players.PlayerAdded:connect(function(player)
	local stats = Instance.new("IntValue", player)
	stats.Name = "leaderstats"
	
	local points = Instance.new("IntValue", stats)
	points.Name = "Points"
	points.Value = 0
end)

-- script for the part that the player clicks
script.Parent.BrickColor = BrickColor.new("Bright green")

enabled = false
script.Parent.ClickDetector.MouseClick:connect(function()
	if enabled == false then 
		enabled = true
		script.Parent.BrickColor = BrickColor.new("Really red")
		local player = game.Players:FindFirstChildOfClass("Player")
		local points = player.leaderstats.Points
		points.Value = points.Value + 1
		wait(3)
		script.Parent.BrickColor = BrickColor.new("Bright green")
		enabled = false
	end
end)

Help would be very much appreciated, thanks!

The event MouseClick has a parameter that tell the script who clicked.

script.Parent.ClickDetector.MouseClick:connect(function(player)

--The player object is saved in the parameter player.
--do your things here
