Well, an interesting game to play, precisely because of the bad starting location.

The first thing to do is of course to get map making: you need both galleys to explore and harbors for food (looks like you lost a lot of time with non-urgent techs like BW, IW, or mysticism).
By putting the science slider to 100%, turning some citizens to scientists and selling some temples, it is easy to research it in 7 turns before running out of gold.
The temples you are currently building will make good prebuilds for harbors. The one in Houston need to be slowed, though. I would switch to barrcks then switch back to temple to lose some shields.

Buffalo also doesnt need temple and is awfully placed. The best move is to join the worker who is sleeping here, make a settler, turn the last citizen into a scientist and abandon the city later.
Another urgent point is to meet the dark green civ N-E of your island. You should build a curragh in Charlotte and send it there, despite the risk on sinking.
