I don't know why we are here on this world and I will tell you one thing I do know - neither does anyone else.
you will get all the correct answers under the sun, sometimes it seems like everyone knows. the theists of all shapes and forms have an ability I lack in that the can comprehend the will of a supreme being, and can deduce from 2000 year old books (amended/translated/lost countless times over the centuries) exactly how they, their children and even random strangers should live their lives.
then you have the atheists, they know there is nothing, they have an ability unlike the theists, they can look into the abyss, scanned every corner and can see clear as day that there is nothing there, the buck stops here on this limited plane of existence.
obviously I selected the extremes as my examples there, or the people from each group who can use the internet to spread their polar opposite views. in real life, most people are more accepting of other peoples views both theists and atheists, they might disagree but are more polite and respectful of each other, I am making this point because the internet isn't the best place for straight answers. it should be, it should be as tolerant as if you were speaking to people in the pub or supermarket, but its not. don't, however, take this as a sign that people are all the same, they aren't. Just take note that, the internet offers some sort of placebo shield to peoples views. this shield not only protects them from other peoples views but it emboldens them to believe only they are correct.
that, mixed with the fact that the loudest people are online BECAUSE no rational people will give them the time of day in real life, is why the internet is so rife with people who "know" the answer arguing and insulting other people who "know" a different answer.
think about this for yourself, do you believe anyone actually knows??
before reading anything else I (or anyone else writes) ill re-iterate the one thing I definitely know and that's that I do not know.
maybe more than that, maybe I CANT know, not in this life.
this does not mean you cannot continually try and work it out. I do, that what brought me to yahoo in the first place. I have my ideas, I have my theories but the most prominent one is this.
this existence can be related to being in the womb. what do babies know of the outside world? they can see bright light but how can they understand it? they can hear sounds, but they cant reproduce them. imagine they had the intelligence to interrogate their surroundings. they could figure out many things from their limited perception but would they figure out what was going to happen??
would they know or recognize the mother from the outside?? would they know that they would need food? water? air??? could they imagine growing up, growing old, talking, running, kissing, loving???
I doubt it, sure, given enough hyper intelligent inquisitive babies, some of them might stumble on the right answers, they have legs, why couldn't they run? they have hands, why couldn't they imagine a pen or a sword or a iphone 6s, but what is the chances??
people will tell you that we have the bible, the Koran, literature that gives the voice and will of god - myself and my wife spoke constantly to our unborn baby, he definitely heard us, he definitely reacted but did he understand his name (we called him elmo at the time)? did he understand the meaning of the songs we sang (she sang, I was banned for being rubbish as I might inflict damage on his tiny ears. Hmph!!). he heard our voices every day, he heard our loving, our arguing, our jokes, our insults but could he grasp their meaning??
to say that we understand gods will (if he exists) is crazy but to say that nothing exists after death is presumptuous. we do have clues, the fact that the universe exists at all in a miracle that science isn't even close to explaining. sure we have the big bang theory but that's only how it started, not where it came from.
the world around us might very well be those sounds and lights through the womb, the disasters and miracles might be the singing and arguing of god knows what on the other side.
I know, its a rubbish analogy once you go to far. does a baby understand even the barest concept of a mother who he lives inside, or a father who he has never touched, or brothers, sisters, aunties, uncles, sister all the way down to midwifes, all of which will play a massive part of the next stage of his existence. highly unlikely and even if it could make rational guesses the chances of it being close to right with the evidence at hand is miniscule.
so bottom line, nobody knows why we are here, nobody knows at all.
but keep asking. keep trying to figure it out.
I know when I sing the same song to my 11 month old son that I sang when he was in the womb, he is comforted (even with my horrible voice) so who knows what you can take with you to wherever we go.
I think we are all going somewhere and we just need to prepare the best we can.
that's my plan.
I sure hope someone is singing to me and that they aren't smoking.
