What if the Bible was a Wiki made long ago by those that got impulse knowledge?
In the beginning God created the heaven and the earth.[CITATION NEEDED]
As for when I'd go back to... I
have thought about this, with no definite conclusion. Mostly what I've thought is that I'd hope that I'd have just enough random knowledge to work out how not to stand out[1] or utterly get it wrong... "Long Live The King!!! Oh, sorry Lieutenant-General Cromwell, what was that you were trying to say to us all?"
I have considered the possibility (should I be forced to choose) of travelling back to an uninhabited desert island, on the basis that I could live on an uninhabited C12th desert island as well or as badly as I could on an uninhabited C21st desert island, without having to worry too much about history. (Just whatever earthquakes, storms, tsunamis, etc, etc occur in that geographical and chronological spot.)
As for "be born in", maybe a decade or two before I was actually born, but that's just for being within my "comfort zone", which of course would not apply if I was completely starting afresh, and would still contain some pitfalls of society like the potential for my stint in National Service to end up sending me into one conflict zone or another, in addition to some of the more interesting elements of social change that I was too young to appreciate at the time in my current timeline.
With some sort of innate knowledge of what I know now (and the self-control not to just blurt it out and get committed/burnt at the stake/forcibly inducted into Hitler's[2] V-Weapon programme/whatever, but just to enjoy things) I could go along with just about any point in history and point of geography, although there are some rather specific examples I'd rather avoid, obviously, and childhood itself would probably be the biggest hurdle.
[1] Actually, standing out wouldn't necessarily be bad. Being "just that little bit foreign" is going to be virtually guaranteed, anyway, unless there's an accent and language converter option in my time-travel kit, and as long as I don't appear to be something like vaguely French in Napoleonic-era England (due to some of my modern language terms, modes of speech and pronunciations being misinterpreted as slips from a spy, among the kind of people who would hang a monkey because they think he's "foreign-looking") I could play on my being from "elsewhere" to cover up any ignorance I have about the era. And there's much more like that, in my various musings, but it starts to get specific to various eras, so I'll stop right there.
[2] With apologies if you consider this a Godwination. Surprised he wasn't already mentioned, save by the non-specific reference to WW2 as a whole.
