We know the answer the moment we could frame a question. Every rung on this ladder represents a question and as we are building the rung, we are getting closer to our answer.
Imagine yourself standing on the ground, seeing what you are seeing and believing that NOTHING else existed. Suddenly you observe a bird in the sky and wonder 'hmm.. where did that come from?' That forms the first rung of your ladder.
Remember though; entrance of that bird is your own creation of clue for your noticing. It is your choice to question or not to question. You automatically do what makes you comfortable; comfortableness is movement and that is what we all want.
