Yes. The Big Bang Theory is very real.

There are four main pieces of evidence to support it:

1. The current expansion of the universe (which, when extrapolated backwards in time, indicates that the universe had to be infinitely dense about 13.7 billion years ago).

2. The cosmic background radiation detected from all directions, which is in precisely the frequency predicted by the Big Bang Theory.

3. The abundance of the primordial elements (helium-4, helium-3, deuterium and lithium-7) and their ratios to the amount of hydrogen is exactly what is predicted by mathematics of the Big Bang model.

4. The development and distribution of galaxies. I.e. the age and distribution of quasars is exactly what is predicted by the Big Bang model.

(Note, this is just a listing, not an explanation. For an explanation, see the source.)

So far, there is no better theory that explains these observations. The Big Bang model predicts them perfectly. I.e. the equations, based on what we know about things like relativity, gravity, and high-energy physics, makes a number of quantitative predictions about these things ... and so far they have all been born out almost exactly as predicted.

Note that this does not mean that the Big Bang is *proven*, just that there is no better theory that explains these specific pieces of evidence. But people who expect "proof" in science, just don't understand science. You prove things in mathematics ... NOT in science. The same applies to EVERYTHING in science.

Personally speaking, I think the "Big Bang" theory is a real theory, but is not the correct one. The reason I base this on is that the theory cannot predict what happens "before" the so-called big bang. I mean when you really think about it, how can you have something being created from nothing, somewhere at a certain time in space ? The only other theory which can satisfy this dilemma is the "Steady State Theory", because it predicts that there never was a beginning or ending for our Universe, but that it has always and will always exit. This might sound like a simplistic view on the subject, but until somebody can think of another theory to explain the continuation of our Universe, it must be considered as a possible theory for explaining our Universes existence !

I've always had doubts about the Big Bang theory. Most of it is based on the expansion of the universe, which implies a smaller state in the past, but not necessarily creation.
I actually have an alternative theory to account for the precieved expansion, but it raises far more questions than it answers. It has to do with the Pioneer Anomoly. To a surprising degree of accuracy, (well within the significant figures of the numbers I had to work with) the acceleration implied by the Pioneer Anomoly matches the acceleration necessary to produce observed red shifting, assuming the universe is NOT expanding. That, of course, leads to the question of what would keep galaxies apart, and it says nothing of the creation of the universe. But if it's true, it would mostly rule out a Big Bang.

The problem with the "BigBang" theory is that just like so many other things in science it is still unprovable. because we cannot go back in time or cross space to other galaxies we are just speculating on what we think might have happened 12 to 15 billion years ago. mind you we can't even say with any certainty how old the universe is or even just our galaxy. If you are really interested in this type of theory you will have many hours of great wondering and still get no closer then when you asked this question today. but here is something to think over just to get you started.

All the galaxies in the know universe travel in different directions. we have pictures that show galaxies colliding with one another. now think of this. If everything all started out at a single piont of origin with a big bang then how is this possible. there are actually 2 answers that jump out of this line of thinking. I'll give you one and you work on the other. the easy one is that there is no single big bang. in fact there may have been many such occurences in the unverse. each galaxy could well constitute its own smaller version of the big bang. many physists are starting to believe that each galaxy has its own supermassive black hole in the center that will eventually implode it. if this happens it is possible that the black hole could reach critical mass and explode, creating a new galaxy, explaining why galaxies vary so much in size, and also preserving the laws of physics, since the universe has dimensions and thus quantity, not infinitly dense specks of matter forming the unverse.

The big bang theory is only a standing theory. They haven't been able to account for all of the mass encompassed in the universe from a simple, but large explosion.
Just like the rest of the theories, it is still only a theory until there is enough conclusive evidence to prove the theory. For now, there are too many gaps, so they try to maintain the theory by interjecting other theories to string the whole concept together. This usually leads to many of the sub-theories dying off as new evidence arises, which also results in new theories being created to maintain the original idea - which is still a theory.

Sounds a little like insanity, doesn't it?

Google "M Theroy" Extremely interesting.

It is a theory, a real theory. All theories are, as yet, unproven. That is to say they are not necessarily wrong or right, just a good, well thought out idea. Once they are proven and reproven, they become fact.
