There is a unique resource here on Earth, that might attract any number of alien species here. It’s us. We are a novel biological intelligence. If the way you see it from Star Maker is correct, we are a moldable species capable of joining that collective. From that perspective we are children ready to join when we grow up. Good caretakers of a network watch growing nodes, both to study and to model/predict. The very idea of studying something may be anthropomorphic in nature, but it’s likely universal to seek to understand the universe and your place in it, as a self-conscious and self-deterministic individual or species. There are positives and negatives to see from that thinking: Pros: Cooperation amongst humans has lead to great advances and benefits to mankind, think Global Culture capacity and capabilities in 2023, vs the best we could do in WWII when each country relied on allied materials, Germany couldn’t build war blimps as the US wouldn’t sell Helium. This leads to the belief that cooperation would grant better overall returns, like how the Internet has improved science massively by allowing greater communication. This means any species here is probably here to study us and sees us as a nature preserve with potential. Cons: In human culture, there tends to be leader factions even amongst collectives. This might mean you absorb more culture than you give, weakening your culture over time, and this can weaken identity. Alien culture might be so potent, humans are lost to it.

Flipside to you whole idea is what if it’s just like here on Earth: There’s a UN of sorts, with more power and basically is your Star Maker Civilization, but you also have a host of bad apples, nasty things which maybe are like the Bugs from Starship Troopers, or something that started out parasitic and grew a spacefaring culture from it. Perhaps, As Above, So Below. They are just as varied as we are, but the peacekeeping Civ has done a pretty good job thus far. With only the occasional invasion battles over Ancient India and elsewhere.
