The original Anthropic Principle is a theoretical explanation of why the conditions of the universe are so perfect for the existence of intelligent life (like us humans on Earth). Why? Because without those conditions, we wouldn't even be here to be making those observations in the first place. Even though the raw probability of those conditions is astronomically unlikely, our very existence requires us to accept that it must have happened somewhere.
