First of all, I am no expert at this game, and play mostly the computer. As far as I understand it Isis is about the most OP civilization that you can go with followed by Oranos and Kronos. Odin is solid too though. The thing is your opponent went into heroic and built his army then. An army of chariot archers and elephants is very hard to contend with unless you make an almost equally big army of their counters. Your opponent filled his/her population to 120. You never got past 55. You never did any economic upgrades.
Some things to do differently: Use great hunt right away on a group of dear, get hunting dogs next time its a map like that ASAP. Build an army of something, and attack. If you want to raid, build plenty of raiding cavalry, and don't be afraid to get them killed.
