This game isn't winnable.
I checked it out with CRpviewer due to compatability problems.
Several problems with the game:
1) 1st city founded in 3750 BC. This is taking up way too much time to find the perfect spot, although it wouldn't matter on Chieftain level if you had expanded more efficiently afterwards.
2) Only five cities by 10 AD and nine cities by 2031 AD, four of which are on islands.
3) I doubt anyone is even near a Diplomatic or Spaceship victory. The Universal Suffrage was created almost at 2000 AD, as well as ToE.
4) Time is simply going to run out. There is no time to turn the game around in any meaningful way, as vxma said.
5) I am not sure what is happening in terms of warfare, but I suspect you are using scattered and few troops. The way you and Egypt seem to just capture each other's cities all game indicates that a lot of time is being wasted on aimless war.
