Conservation of energy is the idea that energy is not created or destroyed in ordinary processes; it only changes form. This is why a light bulb uses electrical energy and emits light and heat, and why a falling object converts gravitational potential energy to kinetic energy while the total amount of energy stays essentially the same (aside from some energy lost as heat). So the true statement is that energy can be converted but not created nor destroyed. The notions that energy can be created or destroyed contradict this fundamental rule, and saying energy cannot be converted ignores countless everyday energy transformations, like in engines or photosynthesis.
