It is more rational to believe humanity is a random by-product of this universe than created by God.

You fairly charge that I haven't answered some of your points:1) Give me one good logical reason why I should obey the law and "love my neighbour" etc if morality is just a by-product of evolution? Why not instead make my life's purpose to exert as much sadistic dictatorial power and control over as many other human beings as possible during my short, pointless existence here on Earth?2) Why not run society like the Nazis? Survival of the fittest/strongest; with no conscience.3) If human life is not "sacred", why not kill off the elderly, sick and unproductive - particularly now on our dangerously overcrowded planet with rapidly declining resources? ---I'd like to start by pointing out that evolution works on two distinct levels, as far as I can see: survival of the fittest individual; survival of the fittest group.We can absolutely identify which of these was afoot when a certain feature was pressured into being. For instance, sharp teeth or efficient guts can be said to be a product of selection of the fittest individual; language skills and empathy, on the other hand, can only be a product of group selection.The greatest assets that mankind has when he faces the natural World are his ability to cooperate and his ability to learn from others. Both of these assets are gifts bestowed upon mankind by group selection.I believe that people are generally kind and loving and forgiving and cooperative. I believe that this is our default position. I do not believe that it would make most people happy to become sadist nazi dictators hell-bent on eugenics and enforced euthenasia. And if I'm honest, quite apart from being shocked that you'd expect an atheist to answer your three questions, I'm offended. I'm offended on behalf of humanity. It strikes me that I have more love and understanding for humans than any theist that I've ever met. And it is when you ask such crass, stupid and offensive questions that you reveal some of the damage that I see belief doing.Let me explain this better: Are you saying that the only reason that we don't behave like swine is because of religion? Are you saying that we'd all be selfish rapist theiving megalomaniacs without the guiding hand of a good book and a good church? I want to tell you in person how I feel about you suggesting that about my noble, decent human brethren.First up, you are factually chatting nonsense. I know, I know... it seems intuitively logical that if people believed that there was a universal overseer, a cosmic babysitter, a divine retributor, a sky-daddy and an eternal punishment for bad children then they would behave better. THIS is one of those stupid persistent myths that religions have made up and people believe them, only atheists often believe the lies too!FACT for your consideration: Murder rates, thefts, teenage pregnancies, alcoholism, drug dependency or any other metric that you care to mention are not greater in less religious communities.Okay, so my tone might have changed (it does when I'm offended), but I beg you to go look that up. You find yourself any evidence that religious belief causes any measurable good in terms of morality and then I will apologise. Up until then, you can take your assumption that everybody who was religious (presumably including yourself) would become wicked if they lost their religion and you can stick it where the sun don't shine. You're either just believing the crap that your wicked religious fellowship has fed you about atheists (go do one) or you are speaking about yourself... if YOU would become the person that you imply in your three questions, were it not for the eternal watchfullness of your chosen imaginary friend, then you frighten me and you are not normal... and if you can see why you would not be such if you lost your religion, why are you bloody asking the questions!?In a softer way: stop, I beg you, ascribing the good nature that you were born with to your religion; that's a mistake, and it's helping you cling on to some stupid bronze-age myths.You yourself said:BUT, and it is a big but, in order to convince me to abandon my Faith and go along with your postulation would require at the very minimum for you to demonstrate that it is more advantageous for me to want to accept that I am just a random by-product of this random universe, rather than a created being with meaning, purpose and significance.Okay, well, let's look at the facts, rather than believing things without evidence. One of things that I've heard religions bleat on about is how much good charitable work and donations they provide. Has anybody ever thought to ask the question as to whether this work is more than the background level of good works and charitable donations made by the secular communities around the World? I have... and I encourage you to do the same... go on, take me up on this and do your research. I'll tell you what you will find:The religious amongst us do give more to charity.But.That is only because our society has given religions special freedoms and tax exemptions and charitable status. Now, if we remove the monies that religions farm from their pliant sheep that are used for building churches, paying for ministries, advertising materials, proselytising missions, campaigning for dubious causes, etc... then we find... we find that the religious amongst us give less to charity than do their secular brothers and sisters. Don't take my word for that, please... please go and find out that fact for yourself. Start thinking about things empirically... start questioning every claim you hear and every assumption that you make... it won't do you any harm!I'll give you my personal answer to why I don't act like your three offensive questions: I am in touch with my better nature without any religious indoctrination; I am happy to be as good as I can. I am happy to have adopted the position that I want to leave the World a better place than I found it and I wish that everybody else would adopt that view too... wasting your time trying to please a celestial bigot who might deign to reward your humble slavish following in a non-existant afterlife seems to me an awful waste of a potentially good human being.And you know what BOTHERS me about this World? You know the sort of things that I would honestly like to change?There exists slavery in the World today. That it still exists and most of us live unaware and uncaring makes me wonder whether we have any right, as a species, to call ourselves civilised. It makes me ashamed to be human to know that such things go on. And I dearly want to make a difference. I am not preoccupied by some potential afterlife, I just want to have the pleasure of knowing that I am putting effort into a good cause (as I feel most people would be).Now, why the virtually militant atheism? Why the "evangelical atheism"? Why is because... because I want the World to be better.Let me give some examples of religion doing harm:The catholic church preaching that condom use is immoral has caused countless millions of deaths; MILLIONS of innocent men, women and children... suffering... and dying... and spreading other diseases... why? Because a bunch of bloody nut-jobs thinks that a man putting a bit of rubber round his John Thomas and seeing to a prostitute is a greater sin than a bunch of berobed bigots preaching to people who might get AIDS and telling them that they're more likely to get AIDS if they use a condom! Seriously, I don't... and I stand in the face of any system of philosophy that can allow this unspeakable immorality.Millions of innocent men women and children also suffer the horrific effects of Vitamin A deficiency. It's a really difficult problem of how to get Vit A to them, but science has an answer: Golden Rice. It's being blocked at every opportunity by another bunch of religious zealots who are obsessed with the notion that genetic modification is a hubristic step too far... GM is kinda stepping on the big man's toes, so to speak. Seriously... there are people who put the potential offense of their imaginary friend as a higher priority than the suffering and death of millions of innocents. I am appalled at the immorality of this. I am appalled at the stupidity of it.There are countless children, and I know some of them personally, who have been so inculcated by the idea of HELL that they live in worse-than-mortal-terror. You know that this is true, right? There are kids who learn to hate themselves out of fear and guilt and a sense of offending a God. And I know that the parents who taught them this believe that they were doing the right thing... but they are not... this is nothing short of child abuse.Now, when I see the millions of innocent men women and children suffering as a direct result of religious belief, what kind of a human being would I be if I didn't try to root out the evil wherever I encountered it?Homophobia, sexism, racism, hatred of people from other religions, etc, etc... you might claim that you never push these things, or that your religion doesn't... but... honestly... you know in your heart of hearts that religion DOES promote these and other offensive and immoral ideas. Whilst it has the bloody cheek to pretend that it's teaching you to be a better person! Utter hypocrisy. Lies, deceit, immorality and wickedness... in the name of all things holy! SO, if you accept that there is no evidence to support a belief in God and you discover (please do the research) that there is no evidence to support the claim that religions make people better people.... and.... religions occassionally cause profoundly wicked things to happen... why, then, would you cling to your belief?It is more rational to believe that we are by-products of a heartless universe than that God did it, but it's also more moral. The universe is already heartless, why worship a heartless God?
