Why isn't the property of my part changing after I called the function?

I successfully got the function to work, but the position of the part will not change after waiting 3 seconds. Can you help me?

function myPart(myPosition)
	local part = Instance.new("Part")
	part.Anchored = true
	part.BrickColor = BrickColor.new("Black")
	part.Position = myPosition
	part.Parent = workspace
	
	return myPart
end

local myPartData = myPart(Vector3.new(2,7,1))
wait(3)
myPartData.Position = Vector3.new(2,7,2)

use myPartData.CFrame = CFrame.new(2,7,2)
