This is untrue - we have explicitly evolved to sleep in the dark. Sleeping in the light is a learned behavior that's more or less an exploitation of a loophole in the circadian clock
...
A specific wavelength may effect you..
That wavelength is not present in moonlight/starlight, which is not "full darkness".
For the vast majority of human evolution, "full darkness" wasn't safe, and wasn't even really possible.
I understand what you and OP are trying to say. And you both kind of have the general idea but none of the details.
Like how you got taught basic things in 6th grade, but by 12 grade you're learning what you thought was the whole truth, was just a general overview.
Which wouldn't be bad if you recognized it, but loads of people want to insist the short summary the learned as a child is as deep as it gets
Oh trust me, I know way more than you think. It is literally my job to study circadian rhythms. I can very comfortably say that you're wrong

For anyone else, I won't try to change your mind.
