The Short Answer

Think of life forms as we understand them as spaceships. They repair themselves when they are damaged, they use fuel to move or power themselves, they take on more fuel, they remove fuel waste, then they use resources around them to make more spaceships (reproduction). The only thing viruses can do is reproduce. They don't use fuel, they don't repair themselves, they don't move on their own. They are like ships that just drift in the cold of space. Then, only when they bump into another spaceship, do their automatic, preprogramed parts start working. They hack the spaceships's own power and own mechanisms to reproduce more viruses. They can hack spaceships to do other things, like move them around to other spaceships, or move within the spaceship. But they don't use any fuel of their own, because they have no way of using fuel (no metabolism). Everything that they do, they have to highjack from a spaceship (living organism), which they do through lines of code that gets injected into the spaceship's code.
