We aren't. We are just the only physical intelligent life.
On Earth ? On The Sun's solar system ? On Milky-way galaxy ? On our Galactic (Milkyway, Andromeda, Large Magellanic Cloud and Small Magellanic Cloud) local cluster ?
Or on what scale ? Do we even know what is the all possible sets of scales ? Who can guarantee, and on what basis that there is not a planet beyond trillions of parsecs where all the possible conditions of development of life and evolution fulfills, and it happened many a years ago ? Or, just in a primitive stage ?
Moreover, in which degree of certainty we could speak that the condition of earth is the only feasible condition of development of intelligent being ?
A very little probability becomes a huge amount, based on how large the population is, and universe is infinite, in true sense .
