Can someone tell me why this raycasting script isn't giving me the right distance?

Whenever I fall from a high distance, it will only print out small amounts like 2.988454 or something. I am not sure why I am getting these small amounts when I should be getting much greater amounts. Can someone help?

--// Fall Damage
local Player = game.Players.LocalPlayer
local Character = Player.Character or Player.CharacterAdded:Wait()
local Humanoid = Character.Humanoid
local Danger = false
local Height = 0
local Despacito = Vector3.new(0,0,0)

Humanoid.StateChanged:Connect(function(state)
    print(state)
    if state == Enum.HumanoidStateType.Freefall then
        Danger = true

        spawn(function()
            while Danger do
                wait()

        local ray = Ray.new(Character.HumanoidRootPart.Position, Vector3.new(0,-1,0)*5000)
        local part, position = workspace:FindPartOnRay(ray, plr.Character, false, true)
        print(part)
        if part.Position ~= Despacito then
            if part.Position == Despacito then return end

        local distance = (Character.HumanoidRootPart.CFrame.p - position).magnitude
        print(distance)
        Height = distance
        Despacito = part.Position 
        end

            end
        end)




    elseif state == Enum.HumanoidStateType.Landed then
        print(Height)
        Danger = false
        Despacito = Vector3.new()
        if Height >= 30 then
            print("SUPER DUPER HIGH oHNO")
        end
    elseif state ~= Enum.HumanoidStateType.Landed and state ~= Enum.HumanoidStateType.Freefall then
        Danger = false
    end
end)
