Use game:GetService("UserInputService")

Or the mouse ig.

USING USERINPUTSERVICE

local IsMouseDown = false
local UIS = game:GetService("UserInputService")

UIS.InputBegan:Connect(function(input, gpe)
——comment this line if you want it to detect even when its a button press.
if gpe then return end

if input.UserInputType == Enum.UserInputType.MouseButton1 then
IsMouseDown = true
end 
end)

UIS.InputEnded:Connect(function(input)
if input.UserInputType == Enum.UserInputType.MouseButton1 then
IsMouseDown = false
end 
end)


while true do
task.wait()

if IsMouseDown then
print("Pressing left mouse button!")
end 
end

USING MOUSE

local IsMouseDown = false
local mouse = game.Players.LocalPlayer:GetMouse()

mouse.Button1Down:Connect(function()
IsMouseDown = true
end)

mouse.Button1Up:Connect(function()
IsMouseDown = false
end)


while true do
task.wait()

if IsMouseDown then
print("Pressing left mouse button!")
end 
end
