Intriguing story with an anthropological mystery that has repercussions for our understanding of history. I like the environments in which the story takes place. I also like the idea behind the story.
But as they delved deeper into their search for answers, the research team was able to explore the city further, and what they discovered left them stunned, they found real evidence of advanced technology, in addition to ruins of structures that seemed to be astronomical observatories and, most shocking, inscriptions carved into rocks, which spoke of the existence of life on other worlds.
I think that for this part, it might be better to focus on one thing instead of many things at once. For example, the story speaks about "evidence of advanced technology" and "inscriptions", but the reader doesn't really get shown that technology or told how the archeologists were able to read the inscriptions. By focusing on one theme or the other, then you can better describe the nature of their grand discovery.
This was a fun and thought-provoking tale. Excellent!
