These are separate variables in the equation. The drake equation multiplies a bunch of probabilities together, one of which is "probability of planet having life" and another is "probability of life becoming technologically sophisticated". A the moment we don't really understand how life starts, so it could be really really unlikely or it could be pretty common. finding independent life events in our solar system means it's pretty common (otherwise it could be 0.00001%). Here's the full equation: https://en.wikipedia.org/wiki/Drake_equation |
