not so bad but illogical

1) Every human constantly produces noise: we can't control our heartbeat, and what we do while we sleep. And it's never said which level of noise attracts these creatures (but they tried to control their breath so i think they can hear even those noises we are used to ourselves, like our own heart) And this couple somehow made a baby!
2) It's a mistake to think that walking barefoot is quiet - it isn't: sand squeaks under feet, the rustle of grass etc , and it would be better to walk in smth soft
3) light signals: somebody has to turn it on in a case of invasion and make it quiet which is just impossible to do with a lever (it would be to noisy)
4) So, the army and scientists couldn't deal with these monsters and a common family became the smartest on the whole planet, but not smart enough to look after their kids. The end just doesn't make a sense to me. And if it was so easy why they didn't try to make it earlier
