"Thanks to new research using data from the Kepler space telescope, it’s estimated that there could be as many as 300 million potentially habitable planets in
our galaxy. Some could even be pretty close, with several likely within 30 light-years of our Sun. The findings will be published in The Astronomical Journal, and research was a collaboration of scientists from NASA, the SETI Institute, and other organizations worldwide."

Note the bolded. Our galaxy. There are an estimated 200 BILLION galaxies. The math on this is staggering.
We are absolutely NOT the only one, nor are our inhabitants likely to be the most intelligent. But, we will all live in isolation from each other because of the sheer vastness of the universe and the impossibility that travel between these specific planets can be completed within the lifetime of most living beings. It's interesting and humbling to remember that, in the big picture, we are insignificant.
