"We" are in one 100,000 year period in over 3.8 billion. 1 in 38,000. No guarantees we survive ourselves. Very rare.
Odds of meeting us, 10 American sextillion (10,000,000,000,000,000,000,000) to 1. Since there are maybe 1 sextillion stars in the observable universe it stands that we could be alone.
How sad, a bunch of fuckups like humanity, holding the bag. I hope to hell we survive and get into space.

I disagree with many of your points.
Jupiter keeps many large bodies from impacting Earth. Rare.
- Most exoplanets that have been discovered are huge gas giants just like jupiter
The sun is at an optimum distance. Rare.
- Many exoplanets have been discovered that are in the goldilocks zone
Our temperature and atmosphere have been relatively stable for over a billion years. Very rare.
- We can't say if this is rare or not, given that we haven't been able to study another planet outside our solar-system to the extent we have earth.
Multicellular creatures evolved. Very rare.
- Again, we cannot say if this is rare or not.
Earth has one large moon. Rare.
- I don't see how having only 1 moon makes or breaks life. Mars is said to once have been habitable but has several.
Our solar system is on an outer arm of the galaxy. No nearby stars affect us. No galactic phenomena threaten us. Very rare.
- Again, we cannot say how rare and we also cannot say how common "galatic phenomena is" given that there's stuff that might happen once per billion years.
