For two oranges to be exactly the same, the following events must happen: first, two identical but individual orange trees would have to be planted at the same place and time. Then, two individual oranges would have to be growing at the same place and time. Finally, they would have to fall at the exact same time and at the exact same spot on the ground to be identical.
Even if the timing aspect is extremely unlikely, theoretically, two oranges being at the same exact spot equals one individual orange. At least on our planet.
If you peel billions of oranges in one go, you would not get the same shape of orange peel twice. Maybe there will be two related ones because you used a similar peeling technique to shape them a certain way. Even if there is a simple way to peel an orange in one piece without making a big mess (Step 1: Start near the top of the orange, right where it was plucked from the tree. Step 2: Peel in a circular motion while placing your thumb right up against the skin. Step 3: Keep your peel wide. Step 4: Show off your amazing peeling skills), the ones I did turned out pretty chaotic but distinctive.
In a world that often tries to make us conform, it is important to remember that our uniqueness is what makes us valuable. To every peel, there was a peeler.
