This argument has never really made sense to me. If you picked a random individual lifeform from anywhere in the universe, then yes, there’s a good chance it won’t have much in common with humans. If you take the totality of all life in the universe however, we should see a smoother distribution of behaviors. Human-like behaviors would be within that spectrum by definition and should not be entirely unique.
Let’s say of all the intelligent species in the universe, an average of 1% exhibit whatever motivations are needed to go interstellar, and that 1% of those species got a billion year headstart. Well, due to sampling bias, we should still see that 0.01% represented everywhere.

Um. The desire to explore is pretty innate to all life. Not just humans.

How much “exploring” do sedentary lifeforms (plants, mussels, etc) really get up to?

Bivalves such as mussels are aware of many stimuli but are generally incapable of safely relocating making them one of the incredibly few exceptions to the rule.
I would generally assume any alien lifeform we encounter would be closer to humans than bivalves.
