Here's a recounting of my France, Tiny, Pangaea, King game.
Turn 75
7, 2, 2 population.
2 spearmen
2 warriors
2 workers
Completed: Wheel, BronzeWorking, Calendar, Trapping.
Civil Service is 8 turns away.
Stonehenge 7 turns away.
3 Monuments. No other buildings.
Social Policies: Tradition 5/6
Notable randomness: Fountain of Youth +10 happy, so ignoring happy science.
Turn 2: +1 pop from ruins.
Turn 250 (1700 AD)
21, 11, 10 population
2 Pikemen
1 Musketeer
3 Crossbowmen
1 Cannon
2 Caravel
2 Workers
Science: Archaeology, Acoustics, Chemistry.
Fertilizer is 2 turns away.
Wonders: Hermitage, Ironworks, National College, Sistine Chapel, Hagia
Sophia, Kremlin, Louvre, Stonehenge, Colossus, NotreDame, National Treasury
Social Policies: Tradition 6/6, Piety 6/6, Freedom 6/6
Culture 272 + 75 + 42 = 399
7 landmarks.
At this point, Science is mainly for defense and production. I don't really
need any more wonders to win. My next focus is to get a bunch of artillery,
and build any helpful buildings (finish my museums, then happiness due to
piety's conversion, then the rest). I hope to win before bombers become any
kind of threat.
Notable randomness: My incredibly weak military score has caused all 3 AI's
to declare war and send armies (even my ally :( ). Sorted them out, but
situation is still risky. I lost a couple workers, and it's hard to build
improvments with enemy units standing on those tiles. However, cities were
never really at risk.
Turn 350
There are 15 enemy units on my lands, a mix of modern infantry and tanks. I have ~6 artillery trying to sort them out... (note from the future: I wind up losing all military that isn't in a city, but I do enough damage to push them back.)
1.5 policies to go. 14 landmarks.
Turn 370
City pop: 25, 19, 17
All policies done. Starting Utopia project. Currently researching Electronics. Did not research Radio.
Turn 390: 1970 AD
Cultural Victory. Whew.
Additional notes: King is much harder than I remember... by the end of the game, one of the AIs was able to field a ~40 military unit offense. Fortunately, he sent it to another AI. I feel the Fountain of Youth greatly influenced my game - I never hit unhappy and I was able to put off Theater science and buildings for a long long time. I feel I built too many wonders at the start of the game and should have instead built more units.
The AI's took all the city states as allies, I never sent any of them any gold. I never had much spare gold to send them either.
I ran a comparatively idyllic prince game (france, pangaea, tiny). Two city'd my way into a cultural victory on turn 317, 1894 AD.
To construct the spaceship, whenever you move a spaceship module to the capital, you need to choose the option to "add" it to the spaceship. The module will disappear and your spaceship will receive it (if it's the first module you add, a 3D model of a spaceship will also appear near the city). This option should be listed at the command bar on the left, just like other unit options.
However, you cannot add modules to the spaceship if one of these applies:
- Another civilization has already completed a spaceship
- You have manually disabled the "science victory" option when you set up the game
- You have already won the game in some other way
As you can see, the 3rd case above applies to you. I'm afraid you cannot conquer the stars in this game... you have no choice but to start another :) enjoy your all-nighter!

Unless you start conquering quickly, you won't be able to conquer enough civilizations in time. My tactic (in difficulty level 5 if I remember correctly) was to immediately use my horseman to conquer the nearby city-state (to the south east) and then the Siamese civilization. It's not an easy war to wage but conquering these cities is a pretty fast way to expand your borders quickly.
Use the terrain to your advantage, as well as the powerful Khan generals and the ranged knights. Avoid fighting in hills until you can get a few pikemen.
I continued to conquer and advance to the south east until I couldn't (that's Siam + China), and then turned my attention west and attacked India and Persia, ending the game on time.
My biggest problem throughout this playthrough was maintaining happiness. Try to prioritize conquering cities with resources and burn down cities that don't really help. The bonuses from city-states are also very nice, so it's recommended you take them as soon as you can afford to.
