Have you read the Grand Design?
No but I read this excerpt on the front page of this thread.

It is possible to turn that last statement into a scientific principle: The fact of our being restricts the characteristics of the kind of environment in which we find ourselves. For example, if we did not know the distance from the Earth to the sun, the fact that beings like us exist would allow us to put bounds on how small or great the Earth-sun separation could be. We need liquid water to exist, and if the Earth were too close, it would all boil off; if it were too far, it would freeze. That principle is called the "weak" anthropic principle.
The weak anthropic principle is not very controversial. But there is a stronger form that is regarded with disdain among some physicists. The strong anthropic principle suggests that the fact that we exist imposes constraints, not just on our environment, but on the possible form and content of the laws of nature themselves.
The idea arose because it is not only the peculiar characteristics of our solar system that seem oddly conducive to the development of human life, but also the characteristics of our entire universeââ¬âand its laws. They appear to have a design that is both tailor-made to support us and, if we are to exist, leaves little room for alteration. That is much more difficult to explain.
