* The more scientific sort is a suggested origin of all life in the Literature/CoDominium universe (at least until ''The Mote in God's Eye'' introduces truly ''alien'' aliens.)

* In Sergey Lukyanenko's ''Literature/ALordFromPlanetEarth'', it is common knowledge among HumanAliens (no StarfishAliens) that life on all of their planers began with intentional panspermia by the mysterious [[{{Precursors}} Seeders]], who also left behind numerous ForgottenTechnology and temples on each planet ([[spoiler:except for Earth]]). What they don't know is that the Seeders are, in fact, [[spoiler:humans from the future, who need an army but do not have the time for a massive breeding program. They send autonomous seeder ships into distant past to spread life and leave behind carefully-selected pieces of technology to accelerate the development of these cultures. They also choose planets in unexplored systems in order to avoid any temporal paradox and ensure that their "children" are unable to get to Earth via conventional means before the time is right]].

* Invoking this trope via exploration, colonization, and eventual terraforming of other worlds is one of the explicit long-term goals of human space research.

Added DiffLines:

* In Creator/NancyKress's ''Crossfire'', this is (or at least is suggested to be) the reason why planets around nearby stars have DNA-based life. Which tends to make things easier for settlers. However, it's shown not to be universal when a plant-like, spacefaring alien species is encountered which is ''not'' DNA-based.

** The Ancients are a race of AdvancedAncientHumans that originated as a splinter faction of the Ori and emigrated to the Milky Way millions of years ago, using their technology to create life in human form in the Milky Way and Pegasus galaxies (on multiple planets in Pegasus, on Earth alone in the Milky Way; the Goa'uld started raiding Earth and [[TransplantedHumans creating slave colonies elsewhere]] way later). [[spoiler:They also inadvertently created the Wraith in Pegasus and were driven out of the galaxy by them.]]

* The BigBad reveals this during his HannibalLecture at the end of the original ''[[VideoGame/XCOMUFODefense X-COM]]'', in an attempt to convince humanity that they should work together. Since the aliens have spent the entire game trying to brutally subjugate and murder the human race, and the aliens have been observed studying humanity as if they had no idea about our species, the point is pretty easily disproven. And then your soldier blows him up.

* In the ''VideoGame/{{Polycon}}'' mod for ''VideoGame/EVNova'', the [[AbusivePrecursors Takari]] created the Polyconians to terraform worlds for Takari use, intending to later employ a "killswitch" virus to exterminate them. Unfortunately for them, some of the Polyconians survived, while the virus jumped species and wiped out the Takari instead.
