In my mind, those gases were created by a series of several consecutive sub-atomic chemical reactions -- one of which got so incredibly dense at one highly specific point that it exploded massively. And so began the universe in the eyes of the skeptic.
I believe in the Big Bang because I see more evidence for it than I do for Creation. Everyday, countless chemical reactions occur in the world to create things that weren't there before. I don't see humans or other things just appearing out of thin air on an everyday basis.
And if God created the Universe, how exactly did God get into the universe in the first place? If you want to use the "Somebody had to make the universe" argument, how did that "somebody" come to exist?
If there's one thing I honestly cannot stand about religion, it's people trying to pass off Intelligent Design as a "science." (I know you said NOTHING about Creation being a science -- I am referring to people who turn Intelligent Design into a court case and sometimes win) Believe what you want, but I don't see how it's "science" if it's a belief and hasn't been approached in its design by any scientific methods. Highly complex things came to exist, as least to me, because several not-as-complex things decided to happen all at the same time, several times, and step-by-step, a complex, really neat thing was created. A lot of people who believe in ID compare it to a clockmaker -- Clocks were too complex to exist by chance, right? Why not humans?
Because this example is flawed. Instead of a fully capable clockmaker making a lot, evolution is like some blind person with no knowledge of anything at all taking a bunch of random parts and indiscriminately making random things with them. Now, a lot of these random things are completely useless. A lot are worse than the parts needed to make them! However, a few of the things that came as a result of this action were improvements. Other blind widget-makers took note of how cool these things were, and told the first person to make more of those things. As those things are make, some of these are not perfectly designed: Some are better than the first prototype, some worse. While this is being hammered out, the next person takes these improved pieces and smashes them together and alters them in the same random way. Some of these prototypes are useless and are not made anymore. Some are more useful than their initial products and are reproduced more frequently. Eventually, as a result of several many occurences of this event and several millions of useless designs that "go extinct" because they are not as good as others, one day a clock is randomly formed. Those who note it see how obscenely useful this item is, and it is reproduced very rapidly over all other designs. Some of these reproductions aren't quite as good, but every so often a mistake is made that makes the clock BETTER. It's noted, and the better mistake clock is now made more frequently.
Only instead of clocks, it's organisms. And this process takes billions upon billions of attempts before a "useful" creature comes to be.
The comment about me feeling outside these forums comes from a few things. Mainly major personality differences. Then again, this is still the best Mario forum I've found, ever, so I'm staying regardless.
Oh, and I'm not trying to turn this into an argument, I merely want to see another perspective of how everything came to be.
