If you are referring to the E=mc^2 equation in saying we are part energy, then this is not true. We are all energy, and yes that energy survives death; the bodies decomposes and it's molecular constituents return to the earth. To say we are part energy requires one to accept that some part of us cannot be described as mass, but this has not been proven, to my knowledge anyway; furthermore, if it was not mass, this equation would not apply and one would, then, have to show why this non-mass based energy form is indestructible.
Being energy also does not demonstrate any particular likeliness for an afterlife due to its property of indestructibility because all matter, living or non-living, consist of non-destructible energy. I think the best argument for a possible after-life would be to show that consciousness is a distinct energy form found to have significantly different properties from non-conscious or non-living matter and also found to not depend on an unique arrangement of organic matter to exist. However, it has not been demonstrated, to my knowledge, that such a distinction exist.

As you must have expected, no one can give this to you. Hence, also why no one can prove there is no afterlife.
