Our Solar System has 8 planets and 1 star; 1 planet has life. Our solar system is in the Milky Way. The milky way has anywhere between 100 billion to 300 billion stars most with their own solar systems of planets. Within these planets it is estimated to be 40 billion or so earth sized planets within a habitable range from their stars. Our galaxy neighbor, Andromeda, has 1 trillion stars with their own solar systems. In the observable universe there it is estimated to be more than 100 billion galaxies.
In our solar system 1/8 of the planets had life, a 12% chance...I'm going to go out on a limb here and say somewhere in those 4,000,000,000,000,000,000,000 (4 sextillion) earth size planets in habitable ranges from their stars (low ball math numbers estimate) there is probably life. And lets not forget about what exists out there than humans cannot even fathom.
There are more than 80,000,080,000,000,000,000,000,000,000 planets out there. Thats 80 Octillion..had to look that one up. And thats a low ball estimate as well going off 8 planets per solar system, 100 billion solar systems per galaxy, 100 billion observable galaxies. I read they have observed almost 200 billion galaxies and the milky way may have 300 billion solar systems..
