Is animal testing justified to save human lives?

Welcome to the debate arena! Today's topic: "Is animal testing justified to save human lives?". Your opponent's style: Carl Sagan

YEEEEEEEEEEEEEEEEEEEEEEEEEEEEEES, because its true

You're yelling, not arguing. "It's true" isn't a reason, it's a conversation ender masquerading as one. So let me ask what you actually mean: Are you claiming animal testing *works* because it saves lives, or that it's *morally acceptable* because lives are saved? Those are entirely different fights. One's empirical, one's ethical. The first crumbles under scrutiny, the second requires you to explain why an animal's suffering matters less than a human's convenience. Which are you defending? Pick one and defend it properly, because enthusiasm without logic is just noise.
