If there was "nothing" before the big bang like people say, explain where all the matter from the big bang came from, how was it created?

    Actually noone knows that. The universal origin story known as the Big Bang postulates that, 13.7 billion years ago, our universe emerged from a singularity — a point of infinite density and gravity — and that before this event, space and time did not exist (which means the Big Bang took place at no place and no time).

    We don't really know"""  At the Big Bang  was the Singularity, when energy created matter. Prior to that, was the VOID. 

    My personal thought on the subject is a 'continuum'. However, the 'Continuum' does not follow a straight line, but a 'wavy' line like the sinusoidal curve.  The Cosmos expands and contracts cyclically.  Currently it is in an expanding mode. because we see objects moving away from us at an ever increasing rate.   This process takes so long as to be incomprehensible.

    --If there was nothing...

    We do not know that there was "nothing".

    However, those who study "nothing" know that (in our universe), absolute nothing appears very unstable - eager to turn into something (and the corresponding anti-something). This has actually been observed, with the "creation" of electrons and anti-electrons (also called positrons). Less common is the creation of larger particles (protons and anti-protons).

    Bigger particles (and the corresponding anti-particles) is less and less probable... but the possibility - as far as we can estimate - is never exactly zero.

    -- like people say...

    Depends what people, I guess. Some "people" say that voting machines were controlled by dead people working for the communists...

    -- the big Bang

    Big Bang is a nickname for a theory that came from the mathematical model of Father Lemaitre, a priest who was also a very good cosmologist and a university teacher. The awful nickname was given by an adversary of the theory (Fred Hoyle) who remembered that Lemaitre had described the start of the universe as the "explosion" of an atom of infinite mass (the so-called singularity).

    But the description of an "explosion" was back in 1927.

    In the early 1930s, Father Lemaitre had worked out a mathematical model to explain the expansion of space itself. By that time, the explosion was no longer mentioned.

    The theory, based on Lemaitre's model, came out in 1948. In the portion called "nucleosynthesis", the authors of the theory do explain how the matter came from the original energy. In 1949, Fred, who had his own theory (Steady State) is the one who came up with the nickname "Big Bang" for the theory that came from the priest's idea.

    (Fred was an atheist who was very much against the idea that the universe could have been "created").

    The Big Bang theory simply describes the effect of the expansion of space upon the energy content of the universe:

    Same total amount of energy + more space to spread it out = the energy density goes down with time.

    The interesting parts come when the value of the energy density (a.k.a. the "temperature" of the universe") passes certain critical values. Matter was "created" when one of those values was passed.

    If you push the theory backwards in time (temperature goes up and up), you reach a point when we no longer understand how things work (the Planck Time, or Planck Moment). Worst, we don't even understand how time itself works at higher densities. This does not mean that time did not exist; it simply means we don't have a clue what it means.

    That is why the word "before" cannot be used at that moment.

    have you even contiinplated  its a long cycle , as in we had the big bang and then matter losses its energy and starts the big squeeze , and endless cycle of expanding and shrinking  , over billions of years . ienstein only partialy explained it  ,

    The most basic Particles of Matter that go on to make protons, Leptons, electrons, etc. are simply "Standing waves" in a single, universal "substrate", possibly "Time-Space"   Whereas "Energy" is a traveling wave.  Different wave attributes like frequency, polarization, etc. and complex wave interactions  form different types of particles.  Nothing is "Solid"---apparent "solidity" is a larger scale effect caused by opposing forces.

    Of course  reality is even more complex ---even allowing for parallel universes, due to other wave attributes and interactions, not to mention a few extra dimensions, but the above is the general idea.    The idea of Matter as little "hard particles" died as far back as the 1920s

    So everything arises from an initiating  "disturbance" in space time----like a stone dropped into a calm puddle

    Guess you never heard of the singularity, presumably with all the mass in the universe.

    Nearly all matter in the universe was created from the pure energy of the singularity during the first three minutes after the start of expansion.  So the creation of matter has nothing to do with the question of what might have existed before the big bang.

    We don't even know whether there ever was a "before the big bang"

    Theory says a tiny space was in a false vacuum state. There was nothing in space, but space itself was in an excited high energy state. Think of a rubber sheet. If you pull it and stretch it, the sheet has tension and potential energy even though there is nothing on it. 

    This potential energy produced repulsive gravity, that started inflation. Space became huge and the excited state dropped to its ground state. That released energy into space and it formed matter and antimatter. 

    Inflation theory does NOT say why the Big Bang occured or where the tiny bit of space came from or why it was in an excited state. Nobody knows those answers.
