I find it hard to comprehend the law of conservation of energy. Allow me to explain my confusion.
I understand that the law of conservation of energy states that energy is neither created nor destroyed. However, it has to come to a point in time where the origin of that energy is magically 'created'. How do we explain that?
For example, you can say that the energy in a falling ball comes from a human lifting and dropping it. Of course, that energy comes from food that we eat, and so on, all the way to the Sun. I know that some of you may be able to explain how the sun gets the energy, etc., but you get my point. I can go all the way back until a single point where you can no long go back.
