Here's a number: a typical virus has under 100 genes, while even the simplest living cell, Mycoplasma, has about 500. That's not a small gap. My opponent's restaurant analogy actually cuts against them: a commuter who eats out still has a metabolism. The virus doesn't eat at all. It's a recipe card, not a cook. Yes, viruses evolve, and that's their strongest point. But prions also replicate and adapt to strains without being alive. Evolution is a consequence of replication, not proof of life. No metabolism, no independent reproduction. Still not alive.
