Dear Gum,
Perhaps some of our problem here is that we are talking apples and oranges.
Your question as to why we are here, has as it's base the assumption that we, as individual beings, are legitimate. The entity you believe yourself to be wants answers pertaining to it's very own little existence, meaning and purpose.
Your questions which pertain to your own individual person-hood, and the other individual person-hoods you see around you, can not be truthfully answered as you hope or wish they could, because (and this is a very BIG because), the person that we believe ourselves to be and the persons we believe others to be, the little entities which are separate from all else, the person you call "me" , and persons we call "them", that exists within capsules of skin, are all, each and every one, MAKE-BELIEVE. They are intellectual and conceptual creations or constructs of the mind. There are bodies running about, but they are not what we truly are, only a very small part.
This, can actually and undeniably be seen first-hand, when (and if) conscious awareness investigates Itself deeply. What remains when identification with a tiny person dissolves, or better said is seen though, is the same exact Consciousness which looks out those eyes now unequivocally understands itself as infinitely vast and unbound. This can not be described as it is too awesome (yet so pristinely unmoving and gentle) for words or for the mind to grasp. It can be and must be seen, realized and lived first-hand to have any real and actual meaning. If not, then it's just seems extreme craziness; as this makes the movie Matrix look like child's play.
There is only ONE Consciousness manifesting as many. When there is true-seeing, then it is unquestionably recognized that the consciousness looking out your eyes and mine, and his and hers, and the cat and dog, and within the tree and the rock, and the moon and the stars is all the same One. There are no more personal and individual questions then; just a deep silent love and respect. Call it God, call it Christ Consciousness or Buddha Mind, words and titles don't matter anymore as they only seem to encapsulate and not reflect the cool-warm freedom and boundlessness.
