As mentioned, especially by Iz, you are probably missing some details really due to lack of experience. Details that really have little to do with combat itself. Some overall guidance about the game would benefit you. Conquering on Noble is very very easy once you learn a few things.
For one, it's clear that you are teching Iron Working which is bad. You can trade for it later after Alpha, which is always a good beeline at this level. Try to put more focus in your tech path. Learn what techs AIs will always tech. And do not tech archery either early.
If you have copper and horse nearby, you have all you need to take out your neighbors early, and if any of those are in your cap's BFC, then you are golden.
So if your goal is early rush with axes or chariots, then make that your focus. Get your worker first. Depending on starting techs, get your food tech and then bronze working. No copper>AH. Teching from that point goes toward normal priorities like Writing>Alpha. And avoid that early religious crap.
Whip and chop out your units. 2pop whipping axes is nice for overflow into the next axe. You should be able to get out 4 to 5 axes in a matter of a few turns, which should be sufficient for the first wave.
It's highly likely that if you focus on this straight away, you will be facing AI warriors for the most part. Eventually, AIs will get archers but you can take them on as well. Look to catch AIs off guard (moving out settlers). If a city appears to have too many archers at a certain point, divert to another city. AIs will move their units around so you can pick them off in the field.
Choking is another nice option. Steals workers, pillage improvements, and make sure they don't hook up metals/horses.
Lastly, Horse Archers are a nice way to run the whole map on Noble, so can focus on that tech early if your goal is simply to run conquest/domination as fast as possible on a noble/pangaea map. Not a tall order to win the game in the BCs. So you might take out an AI or 3 with axes/chariots while using the gold earned to tech HBR. Then switch to Horse Archer production.
Your timeframe for first attack with chariots or axeman, should be more like around 2500 to 2000BC, maybe earlier depending on access to resources.
