Why is distributor pointing away from #1 on TDC?

Thank you everyone for all the input. I’ve heard a few different answers and solutions. Overall if I make sure that the engine is TDC on cylinder #1 and I put the distributor in so that the rotor faces plug wire #1 I should be safe and in good shape. Is that fair to say? If so that is what I will do. So it doesn’t really matter how it is set now or was before as long as when I go to fire it up as stated cylinder 1 TDC rotor facing plug wire #1.
