You're one guy out of 7 billion human beings (not counting zillions of other lifeforms) in a planet part of a solar system having eight planets. Millions of such solar systems make up milky way galaxy. Millions and millions of such galaxies are present in our still expanding universe. I'd bet on existence of life somewhere.
People who says otherwise are just not accepting how much large our universe is. Just because you can't find a fish in a cup of water from an ocean doesn't mean there's no fish in the ocean.
