It is called "story telling."
Yes indeed. The Discovery Channel had a special on the existence of other planets. None have been observed but they already have the size and color and location of these imaginary orbs. [Kind of like building a whole civilization out of a pig's tooth?]
Finally they speculated (they actually said they WOULD find them) that there are probably forms of life on these hostile "gas giant" planets. That raises three questions:
There was anticipated possible life on Mars before the probes. If life isn't on Mars, what makes these geniuses think there will be life on some burning methane ball?
What makes these sciencefictionists certain that microbes in hostile environments didn't adapt from life that evolved (their a priori assumption) under less hostile conditions?
