Remove any of the 12 biological systems. Perturb any of the 37 physical constants. Watch what survives. The argument does not need to be made. It demonstrates itself.
Every living cell runs all twelve systems simultaneously. None is redundant. No intermediate stage is viable. The first cell that worked already had all twelve. Click any card to remove that system and see what the cell loses.
Each constant is set to its actual measured value. The green band shows the viable range. Drag any slider outside the band and watch the universe's state update. The shaded region is the fraction of all possible values that permit matter, stars, chemistry, and life.
Every system is present. Every constant is within its viable range. The argument is not that this is probable. The argument is that probability does not begin to describe what it would take for this to be accidental.
