I'm trying to plan out a story that flips the roles of a 50's giant monster movie that has a human be awakened by cryostasis 20 million years in the future by an bipedal ant species. The human is as big to the ants that a creature of 60m would be to us. Would like the ants to be non colony species, that doesn't lay as many eggs and has developed cites, 50's era technology and weapons that are ineffective against the human. Maybe even have sexual dimorphism with the females being larger (just an idea). I guess my main question is anything of this ant species seems believable or are there ways to it more believable? If you also have any idea what Earth might look like in 20 million years I would apricate any information (I'm having a hard time finding any). I hope this makes sense and hope you have a nice day.
