It's extremely interesting how much the Federation knows about the ancient cultures of the galaxy (e.g. the Tkon, the ancient Bajorans and the Iconians, not to talk about the culture(s) on Tagus III 2 billion years ago for examples)
Wonder how Federation scientists could found out so much about these cultures (in some cases like the Tkon even deciphering and translating their written languages without native speakers or descendants apparently still being around), without needing to rely on the Guardian of Forever or other kinds of time travel.
