  The Anthropic Principle has been with us since the 1970s. This Principle is
advanced to account for the "fine tuning" of the 25 constants of the Standard
Model of Particle Physics. Were these constants very different, life could not
exist. The Anthropic Principle conditions on the existence of life and
concludes that the value of the 25 constants must be within a range that allows
life. The most common further step is to postulate the existence of a vast
multiverse with vastly many combinations of the values of the 25 constants. By
conditioning on our own life, we must be in a universe whose values allow life.
  The Anthropic Principle is commonly held to be untestable because we cannot
be in contact with other universes. I aim here to show the Anthropic Principle
is testable and that its explanatory power is weak: The Principle seems to make
testably false predictions about planet Earth and the life on it. The Anthropic
Principle seems unable to predict the existence of 98 stable atoms, when only
19 small atoms are needed for life.
