Even suggesting that the big bang, a theory backed by well accepted physics and observation, is on the same evidential level as creationism is absurd. Show me the observation, laws of physics, and models that predict creation, and i’ll concede.
This is a nice explanation of how science works, and it’s apparent limitations, thanks.
However, The big bang was not observed, so stating the theory is based on observation is not accurate. Observation of other properties or natural phenomenon and then applying that to the big bang is assumption and conjecture. Reasoned conjecture, but conjecture all the same.
And as any scientist knows, even in very controlled studies there is still wide variability. So applying anything to other than the actual time, place, event, etc that it was observed or occurred is conjecture at best.
Disproving the big bang “model” is not a fair request. You are setting the rules and then saying we have to disprove the theory without disturbing or changing the rules, when in fact, it is these very rules that hold up the model.
Without these rules or theoretical framework the model has little meaning. So in essence you are saying; “try to knock over this chair without touching or disturbing the position of the legs that support it”
Within the “rules” set by creationists, the model has just as much “observation” and theory as the big bang, the rules are just different. And within the context of the human experience, it is just as valid.
For example; show me the positive effect that a belief in the big bang has had on someone’s life. How it has helped the person recover from illness, deal with difficult circumstances, help their fellow man, etc.
Show me how it has help society and bettered mankind on an individual level and I will concede that the big bang model is valid.
Are you following my point?

I follow your points.
First, you don’t quite understand how the big bang was derived or how deduction works in axiomatic theory construction. all of science beyond observation is not merely “conjecture” as you claim. (of course some things are, but, this is another topic) I’ll give you a simple example.
Say that one day you are walking down the road, and you stop just in time to see a man falling to his death. you pull out your handy stop watch and time the man as he falls past the ground floor of a building.
From this information (you now know the height of the ground floor and how long it took him to fall past it) you calculate the velocity that the man hit the ground with. Now, you have just observed and measured an event–you see that a man has fallen to his death and measured his final velocity as such and such a speed. but, you remembering your physics, remember newton’s definitions for acceleration and his law of gravitation.
Now, to sum up to this point, you have physical observation which you know to be true, you also have physical laws that you know to be truth.
Finally, you being a good mathematician, also know about deductive inference. You know that the laws of mathematics are truth preserving. that is, if you start with a true statement, and apply mathematical inference, you will end with a true statement. (this is demonstrated in basic algebra as well).
Then you realize that if you apply newton’s laws to your observation and use some mathematics, that you can figure out how how the person was when they jumped (this is a short calculation: v^2=vi^2+2ad).
Thus, applying a simple mathematical model to observation through implication from physical laws leads you to a new fact–that the man jumped from such and such a height. now, if further investigation turns up that your wrong, and that the man jumped from another floor, you must go back and find what factors you missed. (perhaps the man fell through an awning on his way down, etc…)
anyway, the “big bang” is little different. we have observable data–we observe the propagation of light throughout the universe–and we have physical laws governing the propagation of light.
Through the same sorts of inference from these two things, physicists conclude that at one point all the visible light in the universe was concentrated at a single point, and at some point began expanding outwards.
The key feature now is that this deduction is just like the falling man situation. the observable data is unquestionable, the laws of the propagation of light are considered universally true, and the mathematical inferences that lead to the big bang are truth preserving.
This is not assumption and conjecture like you claim. while of course the big bang itself was not observed, it is directly supported by physical evidence and universal laws.
You may of course argue at this point that what i say is true, but just like in the example of the falling man where the observer forgot to take into account the awning, so too are there factors that scientists today have missed. This though is a hard argument to make with this theory.
I am no astrophysicists, but on my understanding the models that produce the big bang are quite simple (comparatively). Also, the model is all but universally accepted–generally things so well accepted in physics don’t change (without perhaps dramatic paradigm shift).
