Inventing: The process of making something new that no one has created before.
Creativity: Is the ability to think and create new ideas that are original, meaningful and imaginary.
1.Similarities: Both require thinking, and creations are original and special(no one has thought of or done before)
2. Differences: Invention is making the idea into reality- creating the object or plan that he had thought of. Whereas Creativity is only having the idea in one's head, and no work has been done to create an object like that.
3. Inter-relationship: To invent something meaningful and special, need creativity. So in other words, one can't create an invention without creativity.
