I've been trying to find an anwear to this question but the information seems to contradict eachother and I am confused.
I've read that the big bang says the universe emerged from a very hot and dense state, this hot and dense state expanded and cooled rapidly. So presumably the theory just says matter was confined to a very small area where it was very densly packed? That would assume matter existed before the big bang and were not created in it but rather as the universe expanded and cooled it was orderd from the dense mess into ordinary atoms.
But I've also read that all matter was created in the big bang which makes no sense if it was densly packed before.
So I would love to have an final answear was all the matter in the universe created in the Big Bang or did it exist in some state before?

The equations for the "big bang" start with the universe already at a size of about 1.6 x 10^-35 meters. All the mass-energy was already there.

The speculation about what things were like before this is mostly just speculation -- there are no agreed-to set of equations or theory that explain the structure of the very early universe.

If you read that "all matter was created in the big bang", I would suggest that it was just some newspaper reporters' misunderstanding.

Our current understanding of physics fails for times near the instant of the Big Bang. Any ideas about time zero or before are just speculation.

However, there are some plausible hypotheses about times shortly after time zero, say 10^-30 seconds after the Bang. It seems likely that there was a period of "early inflation" sometime between 10^-30 seconds and 10^-9 seconds (a nanosecond), because such a period of inflation solves many more issues with cosmological observations than it causes. But one of the issues it causes is the question of the driving energy of that inflation. The most plausible answer is that it was driven by a phase change in a "false vacuum" state. If true, that means that our space, and all the particle fields in that space were created during that period of early inflation. So, before early inflation: some wierd false vacuum state; after early inflation: all the space and matter as we know it today.

The Big Bang was an explosion of pure energy. Energy and matter are related by the equation E=mc^2. It took time for the energy released by the Big bang to cool enough to form elementary particles of matter. It is hard for the mind to conceive but all the matter and all the energy in the Universe today comes from the Big Bang.

As to what was there before the Big Bang, nobody knows for certain. A spill over from a potential well at God's will would be my guess.

There was no "before" to the Big Bang. It was the start.

There was also no matter at the start, because everything was energy. The matter only condensed out of the energy later.

Lotty: Why did God create the universe to be expanding as if it had started in a big bang, with left over radiation from the bang?

The universe was created,[10 to the minus 95 seconds from zero.] By a single space-time pulse,a single two dimensional singularity,the only singularity that will ever occur in the universe.
The smallest span of time that can exist was created.
The next pulse gave a second dimension setting the shortest distance that can exist in the universe.
The next pulse initiated a single space-time quantum unit that would evolve into the reality that we experience to-day.
Every pulse tripled the units.
It expanded,at an accelerated,for the next 30 billionths of a second,at which time it reached the speed of light and the acceleration stopped.
At this time we have a pure space-time entity of incredible density,About the size of a marble.
There was no gravity,no strong or weak forces and no electro-magnetism. Because the entity was not perfect it contained errors that we call the quantum effect.
This imperfection was the means for the universe to evolve into the universe that we see and experience,to-day.

At the moment our Universe emerged from the multidimensional Greater Cosmos, all forces were equal and unified, at that instant that perfect symmetry broke and gravity separated from the other forces allowing the Universe to inflate at a rapid rate, at .01 to the minus 43rd of a second, as the other forces decoupled from each other, the lines of force combined and froze out to produce matter, energy, and dark matter which make up our current physical Universe. the Universe continues to expand at an increasing rate due to the cosmological constant increasing from dark energy which is the negative vacuum energy of the rest of the cosmos acting on our Universe. Nothing of our Universe existed before the "Big Bang" but the potentials did. Our Universe will continue to expand and will eventually fade into nothingness.

Matter as such did not exist in the cosmic egg (from what we currently know)

It was undifferentiated energy and the 4 basic forces did not exist. There were no protons, electrons or neutrons.

At some point after the universe had cooled significantly particles and then atoms were able to form.

Yes, all matter was created in the big bang. Prior to the big bang, space and time were not unified, but were separate. It was the unification of space with time in the big bang that created matter. Matter is space-time, the unification of space with time.

There has been comment here that nothing came before the big bang. That is speculation that is not part of big bang theory. The universe may well be cyclic, in which case it has all happened before and will happen again.

My answer: There was no big bang, God created everything as you see it from scratch. God has no beginning or end, so this makes sense to me, unlike the somewhat flimsy theory of a big bang that somehow randomly lead to an amazingly intricately designed planet with extremely detailed human beings and animals, from supposedly nothing.

Oh, by the way, if the universe is directed towards kaos, then why have we & the animals around us supposedly evolved to become more intelligent and defined?! Hmm, interesting indeed.
