You have to start off by asking what objective truly is. I know it sounds extremely snobbish but I believe human beings, since we aren't omniscient yet, can never truly know what an objective 'life', 'truth' or 'existence' is be because we are constrained to perceive knowledge only in 3 dimensions (and 4 if time is involved).
To know objectivity first, you must perceive things from a bird's eye viewpoint. That means, you would able to 'objectively' determine truths better in a 2 dimensional space than a 2 dimensional entity. But for the reality that you find yourself living in, you will never truly find objectivity.
