Some answers we stumble upon quickly, easily. This boosts our fragile ego, convincing us that we could find all the answers to the universe, if given enough time.
We are blinded by our own magnificence and don't think for a second that the answers came so quickly for a reason. What if there are buffer questions? What if the answers you've 'found' were set before you to find... so that you might be distracted by their shiny brilliance, by your own shiny brilliance?
There are secrets we fight to find because they aren't meant to be found. Answers that are better left unspoken. What horrors would be unleashed on the world if there were no mysteries in the universe? What horrors would mankind unleash with the knowledge of the universe at its fingertips?
