That's gonna look suspicious. The pre-Crisis version just kind of side-stepped this issue. Johns origin made it look as ridiculous as it is. MOS has a lot of problems and half the town being in on Clark's secret is one of them. Suppose someone moves away? Or tells their spouse when they grow up? "Yeah, there was this kid named Clark when I was growing up who kept saving people. He was, like, really strong!"
