uh thought

it must be tru because when we move our finger we'll give energy to the neighbouring molecule and it is passedfrom that to its neighbour , and from it to next and so on.And we have a law that energy can neither be created nor destroyed , so it will be just passed from one molecule to another infinitely..

I think that question falls into the same category that "If a tree falls where no one can hear it, does it make a sound?" falls in.
