I think my post was deleted so I will rewrite the theory

what if the crewmates are created by the topatt to explore new planets the evidence is the achievement called asemblyng the crew in which you gather all the crewmates thrown around the map and If you get them all and go to a specific ending a type of factory will appear from which things that look like crewmates but small come out, and if that's where the crewmates come from and then after the crewmates grow go to planets and place that the topatts want to explore

but its just a theory

[what?,did you expected, YOU expected me to scream A GAME THEORY.....well then you are right]

A GAME THEORY
