How do i finish the game

I made it to the final part of the map with about 4 million years of evolution to go still. Did i screw myself?

Not even vaguely. There's so much more that you can do to keep evolving. I suggest starting by trying to dodge, intimidate, and kill every type of creature (there are 20 in total). Whilst doing this, you should be able to discover all the different landmarks remaining. If this is still not enough, try to drive creatures towards each other so that they fight amongst themselves.

should i travel back into the map?

It's either that or spend the next few hours doing nothing but passing generations to build up years via babies born.

The people who complain about the game being repetitive are the ones who concern themselves with "finishing" the game.

Personally I found that visiting all the Landmarks on the map was finished enough for me.

I'm not gonna camp at one Settlement and do nothing but make babies, advance generations and evolve for two hours straight just to get to 2m years ago. Why? So I can walk a little further on two legs? That's not my idea of fun and IMHO it's why this game is not more popular.

Make your own goals, make your own fun. When it's not fun anymore, stop playing.
