player:GetMouse().Hit doesn't work, why?

I've tried to fix it so that it uses the mouse's hit, but it still doesn't work. It just says "attempt to index upvalue "mouse".

local remote = game:GetService("ReplicatedStorage"):FindFirstChild("ExploToolCreated")

remote.OnServerEvent:Connect(function(p,player,character,mouse)



    Tool.Activated:Connect(function()

        local hit = mouse.Hit

        hum:LoadAnimation(Anim):Play()
        local bomb = handle:Clone()
        Tool:Destroy()
        root.CFrame = CFrame.new(root.Position, root.Position + Vector3.new(hit.lookVector.x,0,hit.lookVector.z))
        local bv = Instance.new("BodyVelocity")
        bv.MaxForce = Vector3.new(1e8,0,1e8)
        bv.Velocity = hit.lookVector * 100
        bv.Parent = bomb
        bomb.Parent = workspace
    end)

If more code is needed I'll add more.
