Its actually quite easy to make peace with the AI, as mentioned above. Kill them. That's all it takes! But if they're larger than you, that can prove to be a little difficult. So, if they're larger than you, there are three final options:
1. Surrender. Usually not considered conducive to winning the game, and furthering your race.
2. Make alliances with other empires, build up as much as you can, then go on the offensive. When and if that fails, wait for your empire to be totally obliterated.
3. Unleash your ultra powerful secret weapon that no AI race has access to. Its called the......"New Game" button! No AI can match its unparalled power. What it does, it obliterates all your enemies to such an extent that its as if they never existed. Even the star systems change their positions and composition. Only your race can survive, although their technology level may be reduced, along with their number of ships, populations, planets, systems, etc. But you will have attained the ultimate victory over your enemies. Best of all, this weapon can be used an infinite amount of time, or at least until your computer dies on you, because you've clicked "New Game" too many times!!
Of course, this advice is foolish, moronic, and totally made just for a laugh.
