If you had a time machine and unlimited resources, in what way would you unwisely interfere in the time stream? The Aztecs get AKs and smallpox vaccine? The Roman empire plus Communism? Solar panels at the dawn of the industrial revolution? Jimi Hendrix gets an iPhone? Introducing elephants to North America before people make it there? Go wild.
Editing the holy books of every religion to require the daily recitation of "Malaria is from mosquitoes, plague is from fleas, cowpox prevents smallpox, and see attached diagram of a sanitary latrine, please"
i feel like there is a very silly rabbinical argument to be made that maybe this already happened and thats why Leviticus is like that. Like, so many of the laws in the Torah seem to have, in retrospect, very rational and even scientifically sound bases in personal or public health that was, for centuries, totally unthinkable to non-Jews. Maybe I'm repeating an anecdote or disproven historical theory, so apologies in advance, but wasnt there a whole thing during the Black Death in Europe where Jews were much less likely to get the plague? And historians posited that it might have been due to different hygeine practices? EDIT: @nonstandardrepertoire has let me know that this seems to have been debunked.

Obviously the better explanation is that the Torah codified into writing generations' worth of observed wisdom into required ritual practices, and thus this wisdom was able to be passed down rather than forgotten.
Or G-d wrote it. Thats also possible.
