There's so many different thoughts to this.

1.) Earth is in a really special location in that it's a nice distance from the sun, it has a number of much larger planets protecting it with their gravities and the solar system isn't too close to the middle of the Millky Way to be too radioactive. It's in such a perfect location for life that it might be hard to replicate.

2.) There are so many planets circuling so many stars in so many galaxies and life could take so many different forms that it seems mathematically impossible that Earth is the only planet capable of maintaining life. The water on earth didn't come from Earth, it came from the ice on asteroids, so there's definitely water/ice out in the universe...

Yes, there are probably a lot of planets. But life is possible on one in 1000.

Where did you get that number from?

Just guessed. There may be the number 10,000 and 100,000. So far, no one has put all the unknowns into the Drake formula.

I think there is life on other planets but I have no proof. :) It might be that life is so rare in the Universe that most intelligent races will never contact any other.
It seems strange that people have not detected signals of intelligent life from space. And yet it seems to me that it is easier to assume that there is some yet undiscovered explanation for this than to believe that the vast universe has only one intelligent race. For example, perhaps the emergence of intelligent life requires a long period, and perhaps we are among the first to reach a high level of science. Or vice versa, we use dead-end technologies, and have not yet discovered what every other alien race knows. As soon as we make this discovery, it will immediately turn out that you can catch hundreds of thousands of alien TV channels :D

probably never? I wish we could find it in this generation but I don't know if this infinity of possibilities that the universe gives us, we would be able to find life on other planets (before we went extinct)

For sure there is. Just with our limited technology we can´t detect it.
But even with more advanced methods, we may not be able to detect it, because maybe other civilizations out there are hiding themselves. There are so many million planets that most likely some will bear very aggreccive species. Species who send out drones to other worlds, even automated ones, who find and kill any other life forms, e.g. to exploit minerals and what not and bring them to their home world.
At least this would explain the Fermi paradox.
