Animation loads in all players' humanoid?

I've been making a combat system and I just discovered that when one press Q (Key for left punch), everyone on the server left punches? What might be the problem? Please help, thanks!

Server Script:

game.Players.PlayerAdded:Connect(function(player)
	local player = player
	
	local debounce = false

	local leftPunching = false
	local rightPunching = false
	local leftKicking = false
	local rightKicking = false

	local LPcooldown = false
	local RPcooldown = false 
	local LKcooldown = false
	local RKcooldown = false
	
	local function leftPunch()
		local character = player.Character or player.CharacterAdded:Wait()
		local humanoid = character:WaitForChild("Humanoid")

		local leftPunch = script.LeftPunch
		local leftPunchTrack = humanoid:LoadAnimation(leftPunch)
		local leftFist = character:WaitForChild("Left Arm")

		if not LPcooldown then
			LPcooldown = true

			leftPunching = true

			leftPunchTrack:Play()

			wait(1)

			LPcooldown = false

			leftPunching = false
		end 

		leftFist.Touched:Connect(function(hit)
			local humanoid = hit.Parent:FindFirstChildWhichIsA("Humanoid")

			if humanoid and leftPunching then
				if not debounce then
					debounce = true

					humanoid:TakeDamage(10)

					wait(.5)
					debounce = false
				end
			end
		end)
	end
	
	local function rightPunch()
		local character = player.Character or player.CharacterAdded:Wait()
		local humanoid = character:WaitForChild("Humanoid")
		
		local rightPunch = script.RightPunch
		local rightPunchTrack = humanoid:LoadAnimation(rightPunch)
		local rightFist = character:WaitForChild("Right Arm")

		if not RPcooldown then
			RPcooldown = true	

			rightPunching = true

			rightPunchTrack:Play()	

			wait(1)

			RPcooldown = false

			rightPunching = false
		end	

		rightFist.Touched:Connect(function(hit)
			local humanoid = hit.Parent:FindFirstChildWhichIsA("Humanoid")

			if humanoid and rightPunching then	
				if not debounce then
					debounce = true

					humanoid:TakeDamage(10)

					wait(.5)
					debounce = false
				end
			end
		end)
	end	
	
	local function leftKick()
		local character = player.Character or player.CharacterAdded:Wait()
		local humanoid = character:WaitForChild("Humanoid")

		local leftKick = script.LeftKick
		local leftKickTrack = humanoid:LoadAnimation(leftKick)
		local leftFoot = character:WaitForChild("Left Leg")

		if not LKcooldown then
			LKcooldown = true

			leftKicking = true

			leftKickTrack:Play()

			wait(1)

			LKcooldown = false

			leftKicking = false
		end

		leftFoot.Touched:Connect(function(hit)
			local humanoid = hit.Parent:FindFirstChildWhichIsA("Humanoid")

			if humanoid and leftKicking then
				if not debounce then
					debounce = true

					humanoid:TakeDamage(20)

					wait(.5)
					debounce = false
				end
			end
		end)
	end

	local function rightKick()
		local character = player.Character or player.CharacterAdded:Wait()
		local humanoid = character:WaitForChild("Humanoid")

		local rightKick = script.RightKick
		local rightKickTrack = humanoid:LoadAnimation(rightKick)
		local rightFoot = character:WaitForChild("Right Leg")

		if not RKcooldown then
			RKcooldown = true

			rightKicking = true

			rightKickTrack:Play()

			wait(1)

			RKcooldown = false

			rightKicking = false
		end

		rightFoot.Touched:Connect(function(hit)
			local humanoid = hit.Parent:FindFirstChildWhichIsA("Humanoid")

			if humanoid and rightKicking then
				if not debounce then
					debounce = true

					humanoid:TakeDamage(20)

					wait(.5)
					debounce = false
				end
			end
		end)
	end
	
	game.ReplicatedStorage.RemoteLP.OnServerEvent:Connect(leftPunch)
	game.ReplicatedStorage.RemoteRP.OnServerEvent:Connect(rightPunch)
	game.ReplicatedStorage.RemoteLK.OnServerEvent:Connect(leftKick)
	game.ReplicatedStorage.RemoteRK.OnServerEvent:Connect(rightKick)
end)

Client:

local UIS = game:GetService("UserInputService")

UIS.InputBegan:Connect(function(input, gameProcessed)
	if input.KeyCode == Enum.KeyCode.Q then
		game.ReplicatedStorage.RemoteLP:FireServer()		
	end
	
	if input.KeyCode == Enum.KeyCode.E then
		game.ReplicatedStorage.RemoteRP:FireServer()		
	end
	
	if input.KeyCode == Enum.KeyCode.Z then
		game.ReplicatedStorage.RemoteLK:FireServer()		
	end
	
	if input.KeyCode == Enum.KeyCode.C then
		game.ReplicatedStorage.RemoteRK:FireServer()		
	end	
end)
