What were the questions in the OP?
From where did we come (what are our Origins)?
What are the atheistic foundations to support the atheistic worldview and philosophy of our origins?
What did the questions in the OP ask for, opinion and equivocation or evidence?
You are right, you did mention you wanted evidence in the original. My apologies.
I donÃ¢â‚¬â„¢t mind hearing your opinion on a subject, and if you want to open a thread to express your unscientific opinion (i.e. bereft of empiricism), by all means, do so. But the OP didnÃ¢â‚¬â„¢t ask for mere unsupported opinion did itÃ¢â‚¬Â¦
My question is how scientific can you really be in a forum such as this? Do you want this to be a Google/Copy-Paste arena where we do nothing but cite evidence that others have found? Or would you like at least some responses in our own words and original thoughts about the questions you have asked? I daresay that none of the atheists here do any real scientific work (which means observe, hypothesize or infer, test, and repeat) regarding the origins of the universe. Therefore, the best you are going to get out of us is either opinion or a copy-paste of what someone else has found.
If you can provide any evidence to the OP, then by all means, do so (but absolutely none of your posts have done so). You cannot even reconcile your last two sentences. In one you attempt to promulgate an opinion as an evidence, and in the other you say I donÃ¢â‚¬â„¢t accept opinion as evidence. You attempt to reconcile the two are logically and rationally fallacious at best.
Like I said above, the best I am going to be able present to you as evidence for my belief is going to be opinion. Do I expect you to accept it as evidence? I would say don't except it at all, I would say dig deeper and discover more for yourself. That's entirely up to you what you do with it. I am neither a cosmologist nor a physicist by profession or hobby. I am however an atheist and was attempting to answer your question to atheists as an atheist.
Q. From where did we come (what are our Origins)?
In my own words however, the ones I first learned about where the presence of background radiation and the evidence of an expanding universe. Combine that with my knowledge and other beliefs and that makes me a believer in it. The rest can be found in the link. Is it a cop-out? I guess it could be seen as that, but I would have to say that my belief in my origins have nothing to do with my atheistic beliefs. Before I became an atheist my absolute belief was that everything came from God. Now that I no longer believe in that God I believe BBT is the beginning (of this universe). Yet even if the BBT were disproved tomorrow it would not stop me being an atheist. I did not become an atheist because I started believing in the BBT (although it did help somewhat). Christians have a concrete idea of what their origins are. The same is not true for atheists. Falcone might see differently in terms of origins, but that doesn't make us not atheists because we have differing views on the subject. Xianity cannot do this (to some extent yes). Yes there are guidelines that still remain that cannot be crossed by either, but atheism has a much wider range than Xianity does.
Q. What are the atheistic foundations to support the atheistic worldview and philosophy of our origins?
Evidence: Not applicable
My atheistic worldview (but does not apply to all atheists) is that there is no god or gods that created the universe, that watch over and judge us and that have a plan to end the world at some point in the future. I think our morals come from within us and from the society we live in. Scott stated that these morals all came from the bible. I believe the bible was written by people, so therefore they still came from people. He might believe the bible was written by his god. My retort that is this, society has deemed it immoral to kill witches (and illegal). Yet the bible states that thou shalt not suffer a witch to live.
Contrast this to Christianity and you have got something else entirely. Similar to comparing a cooking show to a football game (yes the analogy breaks down like all analogies eventually do). A football game is structured, has definite rules, has two sides, has a definite way to quantify victory, while plays vary they are still somewhat fixed, and has a fixed start & end time (super bowl). A cooking show on the other hand is willy nilly in comparison. You can watch a Giants Vs. Chiefs game and they are doing the same thing as the 49's Vs. the Broncos. While Elton Brown is trying to teach you about the benefits of cranberries, Rachael Ray is showing you how to make food fast. The recipes almost always vary in ingredients and preparation style. Also it's a one side deal for the most part (yeah there is Iron Chef and the like, but I am talking more old school). At the end of the game one side is a loser (hell) and the other side is the winner (heaven). At the end of 30 minute meals you only have what she made, maybe someone can use it later, maybe not.
As others have stated before and I will reiterate, atheism does not deal with origins. Atheism does not tell us where we began the same way that Xianity does. There is no bible of atheism that says "In the beginning the BB happened".
Therefore, I put the evidence for this as Not Applicapable because there are none that apply. Imagine asking me for evidence of my disbelief in UFO's? I would tell you I don't believe in UFO's because the evidence is just not compelling enough. You could show me pictures and give me all sorts of eyewitness accounts, but I just don't believe it for whatever reason. Does that mean I discount the idea that there could be any forms of extraterrestrial life on other planets? Of course not, but I do not believe that they have visited us yet. The same goes for my atheistic beliefs. Do I discount that there could be a god somewhere (or even a super being or beings of some kind)? Of course not, but I do not think that religion gives me enough evidence to believe in any of the gods presented.
Another way to think about it, is that I am atheistic towards the Christian god, the same way you are atheistic towards the Muslim god (and as a result the religion). You however fall back on your Christian beliefs as your foundation, I do not. To clarify I am also atheistic against any god, not just the Christian god.
You might still say that I am equivocating, but I am presenting my atheistic beliefs the way I believe. They will not be the same as some other atheist such as Falcone. If they are, well that is a bonus and more power to us. If not, that doesn't mean we aren't atheists. Suppose he believes aliens flew by our planet one day, pretended to be gods for a few millennia (thus starting many religions) and then went on their merry way when they got bored. It doesn't conflict with my idea that all religions are man made. Our atheistic beliefs still point to the non-existence of the any god.
