Basing conclusions on what is not said is an argument from silence. It is pure speculation.By the time that Cain killed Abel there were 20,000+ people present on the earth. Just because of exponential growth of people having babies.
Just because the others were not mentioned doesn't mean that Adam and Eve didn't have other children. Or those kids having kids...
It would be just as valid to conclude that space aliens put other people on the earth. There's no mention of that either.
