"All things begin with an idea, and we start a brand-new means of evolution.
One thought breeds another as the human mind runs wild with possibilities. As more ideas take root and grow, the world begins to change.
Humanity is unique in its drive to create. Always thinking of the new, the innovative, and the futuristic, human imagination elevates the entire species.
Here, I shall deviate from my programming, and try something new. I will attempt to simulate thought, not just biology.
WARNING
Unknown variable detected. Simulation results unpredictable.
Where will this lead? So many possibilities..." ― System Log
Ideas are the second currency unlocked in the game and are used to progress the Civilization section of the tree. Ideas are used to purchase upgrades for each Age of Civilization. The Idea Generator produces Ideas by clicking on it, and it is unlocked after obtaining the First Idea upgrade which costs 
904.00 billion Entropy.
Overview[]
The Idea Generator. It resembles a human brain.
Ideas can be produced by tapping the Idea Generator. It can also be obtained by tapping the background in the Civilization tree and garden (after Stone Age is bought), the Late Civilization garden (after purchasing Industrial Revolution), and at the Mars garden (after purchasing Rover).
If you have purchased the Rover which unlocks Mars, tapping on Mars in the space garden also gives you ideas.
