These galaxies are in average 50 millions light years away and that is also seen in only 1 degree wide view in the sky. Billions and billions stars 100s of times greater than sun in those galaxies. Its insane to claim that we are alone in this universe. There may be millions of earth like objects in the universe spanning millions and billions light years away. Will we ever come in contact with them?
