I think the Carar in NS2 and Subnautica is like the Symbiotes from the Marvel franchise. There are two types, one is benevolent while the other is malevolent. Based on this idea, here's my theory/story on the Carar's existence.

Many eons ago, the Precursors created the first Carar strain for unknown intentions. Upon discovering the Kharaa race, they decided to use them as experiments for the bacterium. This strain was benevolent, as it allowed the Kharaa to evolve into a unified hive intelligence over the course of possibly thousands if not millions of years. However, the Kharaa became too aggressive and forced the Precursors occupying their planet to flee. This prompted the Precursors to consider developing a cure to prevent the Carar from overwhelming the galaxy, which eventually led them to Planet 4546B. After colonizing 4546B, the Precursors created a new Carar strain that was much more aggressive and designed to spread much faster than its predecessor. This strain was to see how it affected organisms in real-time instead of millions of years so the Precursors could develop a cure without having to wait for results. During their experiments, a Sea Dragon Leviathan infected with the strain went berserk and destroyed the Disease Research Facility, unleashing the strain and killing 143 billion creatures. The Precursors fled the planet, but since they feared it would spread throughout the galaxy, a group of Precursors stayed behind to install defenses such as the Quarantine Enforcement Platform and the Warpers before uploading their minds to computers and sealing themselves away to await retrieval. However, no one returned for them and after 1,000 years, they are still waiting.

Took me a while to figure out how to connect the two games, but let me know what you think. It views the Precursors as careless scientists who fell victim to the consequences of their actions in their blind pursuit of knowledge.
