Existing in Existentialism

Look around you and chose one unsuspecting victim for this experiment. You only question will be “why do you exist and what’s your reason for existing. Rather, what is the goal of your existence?
This is a very heavy question, one often avoided, fairly evident when you run out of topics of conversation and would yet talk about the weather than existentialist dilemmas. Obviously I’d ask you, for this particular experiment to refrain from asking a religious or spiritual person of any kind. I’d be able to simulate their answer as easily as you would after some basic information on comparative religion studies.
The secondary purposes for existing are often ones added onto the main objective of “I exist because I am”. Now that, is a sufficiently good reason to exist, yet, isn’t completely accurate in describing why anyone would continue to do so. The quick reply that thought almost necessitates is that existing requires no effort as opposed to not existing wherein you have to consciously make an effort to not exist. This is quickly rubbished. Existing is far tougher and consumes far more effort in one lifetime, than the effort required ceasing your life a million times over. Yet, we’re incapable of self cessation.
Hobbies, Arts, Likes and activities of both aesthetically and physically pleasing natures are bought in to explain the further reason for existing. The common ones being good food, good music (musicians), family, art and so on. These while being good explanations created out of socio-economic factors like your immediate company, or even factors like religion, region, and genetic disposition all explain WHY you are as you are. Once realized WHY and HOW you already function, the real reason is, can you continue to function the same way. I feel almost compelled to further explain this.
So I shall.
The red and blue pill from the Matrix trilogies. Almost all of us would chose the pill allowing for us to remain deeply buried within the comfortable embrace of the world we know. Finding out the truth does absolutely negligible amounts for our want to live in the truth and we sooner revert than hear any more.
The absolute truth in this matter (according to me) is that we’re programmed animals. We feel most emotions because that’s how we’re evolved and that’s how we’re been taught to feel or emote. This is evident by how certain emotions associated with certain actions don’t transcend well across different cultures.
What then is the purpose for existing?
We know HOW we’re here, we know WHAT we’re made of, We know WHY we’ve existed and flourished so far, but what now?
I’ve written before about how “unconditional love” is just a mere concept more than reality and nothing is capable of unconditional love, not even a god, indicative by how EVERY religion has a concept of hell. If pure love as written doesn’t not exist, the love we know is a hormone driven short-term concept which is later put on auto-pilot by various other chemical reactions that we could name, what’s the purpose of existing? Can our mundane short term “ambitions”, needs, goals and need for self propagation be enough to justify existing?
