Still waiting for that easy math equation that proves me wrong, though. Perhaps you could get to sharing it instead of continuing the personal shots. They’re really boring and I’d rather stop wasting my time if you don’t actually have anything interesting to teach and were just lying about it. As an educator I’m sure you can appreciate my interest in learning, so I’d appreciate if you could put your personal grudge aside and just get on with the thing that proves me wrong.

Jesus Pep, start with Drake. I personally hate Drake because it relies on some really bad assumptions and bad variables. But start there to get something theoretical going. And then start looking at what we have discovered in the past 60+ years since Drake.
Cosmologists estimate there are between 200 and 400 billion stars in the Milky Way galaxy alone. We may think that is big, but the closest galaxies to us are two to four times in size. Even if you think the Milky Way is an average sized galaxy you have to then understand that with data from Hubble, Kepler, and Webb it is estimated there are two trillion galaxies in the known universe. Galaxy IC 1101, the largest we've studied, is 5.5 light years across and is estimated to house 100 trillion stars all by itself. 100 trillion in one galaxy alone. Even if you take a middling projection of the Milky Way and use it as the basis for a start, that's 300 billion stars times two trillion galaxies. That's an estimated 600,000,000,000,000,000,000,000 (6.e+23) stars. Multiply that by the number of planets in the Goldilocks zone. If the building blocks exist on two planets (that we know of) in our tiny solar system, how unique do you think it's going to be. Start working the odds. Start working the bell curve.
