A theory is proof that humanity cannot truly ever start from scratch. If we could, we would create universes out of nothing, birthing matter at will. But theories? Is but a question. A starting point. Something to work with in order to gain a better understanding, or creating something new, or to prove something old.

In this case, it is perfect for highlighting the fact that we are always striving to become something else, something better. And that we had to start somewhere. We had to work with something, in order to create something else.
A musician might play with sounds in order to create a tune as a test, then begin composing something more complex. A artist might begin with sketches before committing to a scene they finalise. A physicist might begin with a question which would then become a theory and thus, begin to prove its existence or lack thereof.

Everything we think we want to do is only in theory, until put into action, even the smallest of actions.
