I'm confused about what you are trying to accomplish. Let me start with a state assessment, both to summarize my initial impressions and to help others weigh in without having to open the save file.
It's turn 170 (standard speed, large pangea map), and you have 8 cities -- capital with 9 pop, another city at 10 pop, 2 at 8 pop, and the remaining 4 at 7, 5, 4 and 2 pop. You have a settler about to found another city, but happiness may not support another city with no new unique luxuries
Although you have libraries in all cities except the smallest one (and have plenty of gold (621 gold) to buy a libraray in that city), you haven't built the National College and only 1 city (your 10 pop city) has a unviersity, and that one is on gold focus, running a market specialist. In fact, you are running market specialists in two other cities that are also on gold focus. As a result, you are only generating 86 beakers per turn. Nonetheless you entered into an RA with Darius 14 turns ago, which isn't going to be very cost-effective unless you really focus on generating beakers. In fact, one of your cities is on science focus, but only generating 7 beakers--kind of pointless. Within 9 turns you can have universities in 4 cities, with working specialists (taking beakers well over 130 per turn), and I would recommend that you do so.
You have completed Liberty and are 3 policies into honor (opener, warrior code and discipline). You aren't in the Renaissance yet (you can tech Acoustics, but are finishing Compass right now, for reasons I don't understand--only two of your cities are next to mountains, so obsrvatories should not be a priority, and your coastal cities aren't in immediate need of harbors). Your next social policy can be adopted in about 18 turns, so with appropriate tech order and your maturing RA, a belated jump into Rationalism should be possible. Four other civs are in the Renaissance (including all three of your immediate neighbors), but you haven't assigned your spy to any task. I would recommend spying on Alex ASAP.
No current wars, and it looks like you settled your war with Washington 14 turns ago on terms where Washington paid you some gold plus gpt. Looks like you had one earlier war (Darius - white peace on turn 102). You nearest neighbors are Darius (DOF and RA), Alex (who says he's friendly, but is grumpy that you breached a promise to remove your troops from someelse's borders and that you have a DOF with Darius, with whom he is at war--he's only willing to pay 172 gold for your furs, so a DOW is likely once he's down with his war with Darius), and Washington (your relationship is all negative modifiers, he has denounced you, and he is also at war with Darius). Darius has 9 citiies, Alex has 13 cities and Washington has 2 cities, plus a puppeted CS, and all three are in the Renaissance.
On the military front, because you are behind in tech, you are a bit underpowered for such dangerous neighbors. You have a small army of comp bows, catapults, and longswords near Washington's capital, but he has minutemen, pikes and trebuchets, so you are a bit outmatched. You need to get to machinery, upgrade your comp bows, and tech to gunpowder as soon as you can, upgrading your cats and swords, before taking on any of your neighbors.
On the gold front, you are generating 42 gpt, but 27 of that is from the peace deal and various part lump sum gold/part gpt trade deals (which seems to be typical post-patch) and some of the rest comes from the gold focus. The diplo overview says most of your trading partners are friendly, but your deal terms seem to be below market, some of which is due to trading with Alex and Washington. Have you been just taking what the AI offers, or have you been counter-offering to get to market terms? (Actually, as I look at it again, it looks like you are close to quick speed pricing--do you normally play quick games?)
So, you aren't in terrible shape--kind of middle of the pack in this game, which is good for your first Emperor game. Domination is probably your best bet, but you need to get caught up on tech in order to have real options. Rush build the NC and your universities, work the university specialist slots, jump into rationalism as your next policy, focus on getting your pop up, and get on at least tech parity with Washington before taking him out. Greece will be your biggest challenge, but Athens is near by and on an open plain, so may be easier to take than, say, Washington.
'Nuff for now. I'm going to play around a little further with your save.
