If a gas giant were in the Goldilocks zone of a Type G or K star, say, there might still be possibilities for life if the gas giant has one or more large moons. Maybe?
I think the modern bedrock assumption is that abio genesis and evolution sprung up here on earth ... SO surely it must have done so on another planet as well.
That is the assumption I think driving the search for life on other planets.

@deepthoughtsaid but I do think it's likely we're rare. To the extent that we could be the only extant technological species in the galaxy.
And if this is true for every Galaxy in the observable Universe there should be about 200-2000 billion technological species in the Universe. Not so rare anymore in my opinion.
"One of the most fundamental questions in astronomy is that of just how many galaxies the universe contains. The landmark Hubble Deep Field, taken in the mid-1990s, gave the first real insight into the universe's galaxy population. Subsequent sensitive observations such as Hubble's Ultra Deep Field revealed a myriad of faint galaxies. This led to an estimate that the observable universe contained about 200 billion galaxies.
The new research shows that this estimate is at least 10 times too low."

That's right. I have gazed at that picture for long periods of time in total wonderment.
But so far, our sample size of planets where life exists is 1.
So far.
