Assume you have all the luxuries of a modern life in your Tardis (toilet, hot showers, TV, books, game console, …) which doubles as a mini self-sufficient apartment with it’s own energy stores and generation.
Where in history would you go if comfort wasn’t an issue?
I’d check out and record all of the Biblical/Qur’anic big moments at a prudent distance, probably (barring the times of Noah, lol). Then I’d die in the time machine as I try to come back to my time and share with others cause God wants belief in the unseen and through uncertainty, maybe. 😅
