During the inception of our Universe, fortuitously arose a small possibility that under certain circumstances there might come into existence at least a single primitive intelligent being. The planet upon which this would occur remained a mystery, and the emergence of intelligence on Earth is not miraculous. This could have materialized on another celestial body, and a thinking being similar to us would likewise ponder: why us, why here? It's a matter of chance, you're simply fortunate, your planet won the cosmic lottery.
