[Justice League 2017] What is it about the rocket Cyborg fires at Steppenwolf, that compels Steppenwolf to declare Earth's inhabitants as "primitive beings"?

I mean, I get that he's all-powerful and stuff. I guess my question is more about the DC universe, particularly: is there something about the construction of the rocket that Steppenwolf would find to be primitive? Does he recognize it as such, or is he merely commenting on the fact that he's able to catch it with no problem? Or something else?

Asking for a friend.

It's an explosive device propelled by a basic chemical reaction, contained within a simple metal casing, and with a chemically explosive payload.  For someone like Steppenwolf, who deals with technology on the level of Mother Boxes and boom tubes, a simple rocket is child's play.  Plus, it's not even a particularly powerful rocket by Steppenwolf's standards, because he could catch it mid-flight and hold it with one hand, and he was completely unaffected by the detonation.  

For an analogy, picture a monkey throwing its feces at you.  That's approximately how threatened Steppenwolf was by Batman's rocket, and also approximately equivalent to how much disdain Steppenwolf felt at this lower life form daring to think it could hurt him with such crudeness.
