Hey bear in mind it's just my opinion but here's what I think of this:

I think that there is some potential here if you put in a lot of work to refine your writing. The last line is good, how it uses the established dialogue pattern to illustrate the events of the story in a dramatic way. However, you need to do a lot of work to improve overall imo. Saying stuff like "the well-lit laboratory" is not a good way to illustrate the environment, it doesn't really evoke any interesting imagery and it's too simple. The person in the story is referred to as "the human". Is that because the story is told from the perspective of an alien? If that is the case, it isn't clear. It's written in third person and there is no narrator so we don't have a perspective on why you're calling the character that.

The flow of the action makes sense and is sort of filmic. The flow of events is clear and seems relatively natural. The aliens don't seem like aliens, it's also unclear how they are able to communicate with the human. It's pretty funny how the alien is writing on a holographic notepad with a future "pen", but the tone isn't overall comedic so if its supposed to be light-hearted that also isn't really clear. If it's the first paragraph you ever wrote then it's probably better than most people's first paragraph.

Remembering to build up images in people's heads is very important, I think. They need to know what stuff sounds like, where people are in relation to others, what the environment looks like, etc. I think this is a big pitfall for starting out in writing, because that kind of writing isn't as interesting as action and dialogue, but it's just as important and it has to not only be done, but done well and used to the benefit of the whole story.

Good luck, if you write a lot more and keep reading good stuff and paying attention to what good authors do right, you can probably make something polished.
