Definitions for "Anthropic principle"
scientific theory based on the idea that “the laws of physics that we observe are determined not by fundamental laws, but instead by the requirement that intelligent life can exist to observe them.
This idea says that the seemingly arbitrary and unrelated constants in physics have one strange thing in common--these are precisely the values you need if you want to have a Universe capable of producing life. Note that there are many variants of this principle such as the strong and the weak anthropic principle.
We see the universe the way it is because if it were different we would not be here to observe it.
