| It's the only theory that explains the beginning of the universe, and is widely recognized as legitimate by scientists. It has an enormous amount of evidence behind it (I will list it out, if you want), and there has never been anything that contradicts it. |

| True rationalists call it a possibility because it hasn't been completely proven yet. Also, if you knew anything about the Big Bang Theory, you wouldn't say that it explains the complete creation of the universe, because it doesn't explain it by itself. All it explains is the motion of the universe. |

| I think a greater possibility is that the universe experiences several big bangs, but none were the beginning. It could go through a series of big bangs and big crunches (or other end-world scenarios) on an infinite timeline with no true beginning. |

And background radiation. And the abundance of hydrogen. And deuterium.
As for the "it hasn't been completely proven yet", neither has the theory of universal gravitation. |

| You're right, it's not a possibility: it's either true, or it's not. It's legitimacy is, however, entirely up to whoever is analyzing it. There will never be a way to prove its validity. |

Yes, this is a very widely regarded theory, but it does not contradict the big bang, it adds to it. |

Here is a fun fact:
Before anyone sent anything into space, astrophysicists using the big bang theory were able to accurately predict the temperature of space, and were off by half a degree. This is one of the most accurate calculations based on a theory in history. |

| Oh, really? That's awesome. I love reading about anything pertaining to our universe. |

@Awesome
I still refuse to completely agree with any theory unless irrefutable evidence is given. I will hold some ideas on a higher level of probability, but I won't act as if it's fact. |

I don't really see how someone can explain the ever-increasing distance between the galaxies with something other than the big bang theory, though.
Oh, and I don't capitalize it because, sadly, most people thing I'm talking about the show when I do. ._. |

I believe the big bang wasn't the beginning, even though I believe it happened. I believe in a non-personal God that started the big bang by design. I don't think any other explanations are as likely, because design is much more probably than physical necessity, and with that, more probable than chance. |

I don't see much of another possibility either.
But hey, you never know.
@Eterra
Maybe. Although, there are just too many factors to take into account when trying to choose the reality that you want to believe in, that it's really hard to know for sure. |

Here's how it happened:
We observed that the universe was expanding. We used red-shift, Doppler effect, etc, you probably already know that. Based on the rate of expansion we observed, we were able to regress how long ago it was all in one place. We did not know it all came from one place, we just knew that it was expanding, and that if it did come from a point, then it started expanding from that point about 13.75 billion years ago.
We discovered deuterium, which is a hydrogen isotope that can not possibly be created in stars. It requires an environment much, much hotter, and we discovered A LOT of it. Because of this, we figured the universe probably came from a pretty small point, where there would be sufficient heat to create a lot of deuterium. Now we are pretty sure that it started in a single point 13.75 billion years ago, and is expanding.
Based on this, we figured that there must be a lot of energy left over all over the place, and so "just for fun", we decided to calculate just how hot space is, on average.
Now we go into space, and find that space is almost exactly as hot as it was predicted to be.
If you see a flaw in any o=of this reasoning, tell someone. |
