I moved the settler 1N, and on the second turn I decided to move it 1W to settle on top of the silk and get some flood plains and riverside.

Our scout dies early by 2 attacking lions. The scouted area so far (3480 BC):
I decide to settle the horse city next.
1 turn later KK shows up and I think it's time to try this immortal rush everyone is talking about.
At 1640BC I manage to scout the mongolian border
Also, Stonehenge build in a distant land.
1560BC - I realize I am not sure what I am doing so I decide to stop and think

.
The persian empire:
I stop here since I am not sure if my rushing plan is good anymore.
KK has been slow settling the north, I could whip & chop settlers and crush my economy blocking him.
Regardless of whether I rush him or not, great lighthouse looks attractive for this island, especially if we meed foreign AIs. scouting with another workboat is important here.
I am not sure how to prioritize all the options. If he gets a metal the rushing window is over, so I need to hurry up there, but then I will lose the GL.
If I want the GL I should probably have 2 workers in Parasgadae and chagne research to sailing->masonry, but that will slow down the rush.
I could also rush to the stone and build pyramids, but I think it is less attractive on early game for charismatic who gets +2 happy right from the start.
I know it is difficult to give advice without spoilers if you already played this game and know some key factors (are we isolated? does KK have metal?), but please try to base your advice on my game so far rather than your game.
My current thoughts - there is no bronze on this island, and I don't think KK has iron working yet. I could try to do both rushing and GL.
Paras will build/chop GL, while the other 2 cities will do immorals.
I don't think the island is big enough for both of us, so peaceful settling doesn't seem attractive, even if I manage to block.
