As we all know, according to physics law, energy cannot be created nor destroyed but can transformed from one form to another. this is just my curiousity. everything that exists must be created from something. is it energy we using today is originated from energy that several perhaps million years ago? im not so sure if someone can understand what im trying to imply..

those energy must be created from something right? for example, sun's energy is created from the nuclear fussion inside the sun.

thanks for all of your comments although some of it is too complex for me to understand however why energy cannot be created? can someone explain?
