The Anthropic Principle is NOT a tautology

The fact that conditions be conducive and that we exist must necessarily be true does not make for a cosmological principle.

The fact that the actual observed structure of the universe occurs in dramatic contrast to the modeled expectation... where *many* fixed balance points are commonly or "coincidentally" pointing directly toward carbon-based life, *does* indicate that there is some good physical reason for this otherwise completely unexpected structuring, that is somehow "specially" related to the existence of carbon-based life.

The Anthropic Principle is a cosmological principle, so you most certainly *can* falsify it if you can show that the *surprising* configuration that we ended up with isn't contingent on the existence of carbon-based life, as is indicated by the physics that drove physicists to formalize the observtion as an "ecological correction" to the cosmological principle, which erroneously extends mediocrity where it does not apply.
