Our nearest galaxy. The most recent estimate of the number of galaxies in the observable universe is approximately 2 trillion. And each galaxy averages about 300 billion stars. That adds up to about 3 billion trillion stars in the universe. Each with planets orbiting them. Some with life on them, and some of them with intelligent life. Even if the odds of intelligent life are 1 trillion to 1, there would still be 3 billion stars with intelligent life on one of its orbiting planets.
