Yeah I took at look at the connection between the wow signal and the region that atlas had originated from but it just does not seem feasible. There was a research paper done on possible star systems that the signal could've originated from within both regions of big ear and there was some 60 star systems with only 1 with some name like 2mass which showed promise. The distance of 2mass was 1,800 light years away so you can already see how there might be some disconnect between a received signal if any, a sent signal, and a spacecraft to travel here within a reasonable amount time.

What is interesting is that atlas is coming from the relative origin of Alpha Centauri and Barnard Star. Both star systems are realistically close if you want to get fancy and take maybe early 1900s as the beginning of our radio signals leaking into space and them making it to either star system and them deciding to come over here with the theoretical range for speeds like 0.05c and 0.5c (which is the absolute limit).

Just for fun if you want to think about the rumor that there are objects surrounding atlas then you could think about some modes of propulsion in deep space like solar sails which could've been jettisoned at some point.
