Need help beating AI on hard mode

Hi, first post here. I'm a huge aom fan and I've been playing the game (extended edition, but play mostly with Greeks) a lot recently. I've become very skilled at moderate mode. Still I can't defeat the enemy on hard. He advances much fastrr than me and is always sending soldiers to attack my villagers. Also, his economy is very well balanced. No matter how much I attack his mines and forests I don't seem to damage his economy . Do you guys have tips?
