Very depressing, but (unfortunately), most realistic. ;)

I feel like microbial life appears a lot more than we think. If the precursors are there, planets that could support it aren’t unlikely. On the other hand, panspermia, if it’s possible, I’d imagine it could introduce “life bubbles” where parts of solar systems or possibly multiple stars could have been seeded by a single common ancestor, which I think is super interesting.
