Origin
The origin is at CFrame.new(0,0,0,0,0,0,0,0,0,0,0,0), or Vector3.new(0,0,0)

Because the formFactor of most parts starts as "Brick", it has a size of 1.2 meaning that the starting position is 0.6

GUI Origin (UDim2)
GUIs have the origin of UDim2.new(0,0,0,0), where the size and positions have scales and offsets of 0 on both axes.
