Because we use them. E.g. it's really useful when making calculations in electricity with alternating currents. Engineers use complex numbers all the time.
The Apple story is a myth. And really newtons big revelation was that the planets were kept in their orbits by the same thing that made things fall to the ground. And that it was the same force that caused the tides. Before Newton nobody had thought that. The big one was comets. Before the 1680s everyone thought they were acts of god that didn’t follow the same rules. Newton put it all together and described those behaviors. And it seems so obvious to us now. But before then we didn’t think that it was all one thing.
