If cause an effect is true. What created the universe, and what created that?

Some things are better left unasked! I believe that it is only our nature to ask such a thing. We should stop worrying about these things and live our life to the fullest!

Well i am Christian so i believe that my God made it, and what made Him we don't know, and may or may not ever know, but no science has no evidence and never will because they never seem to live long enough to make their "eureka!" moments happen

At the quantum level, "cause and effect" is not true as a matter of observational fact, and so your question is irrelevant to the real universe.

There are many speculative theories that try to put the Big Bang into a bigger picture - what caused it, what was before, etc.

One of them is the inflationary model, which pictures the Big Bang as a "bubble" of matter that appeared and expanded out of the vacuum that hasn't decayed to it's ground state. It also implies that elsewhere in the vacuum, there may be other universes.

To understand how it works, you need to know the quantum-mechanical definition of vacuum and what goes on in there. Basically, empty space is never really empty, but contains some energy and creates virtual particles. If vacuum has slightly more energy than it should have, this can produce matter, which would then rapidly expand, creating a Big Bang. This is what is thought to have started the Big Bang which created our universe.

It is possible that some things "exist", without being created.

For example, mathematics.  Does it exist?  Was it created?  The answer may be that yes, it does exist and no, it wasn't created.  There is no way it could be different from what it is, and any inquiring mind can "discover" it.

The "laws of physics" may be like that.  They may be a logical necessity, and may exist without being designed or created.  This is, however, just speculation.

Given the laws of physics, it's likely that the Big Bang was a rare quantum event.  The total energy content of the Universe is zero (since it is observed to have a flat geometry), and so no energy is needed to start the Big Bang.   The matter and other stuff is balanced by the negative gravitational energy of the Universe as a whole.

Since we know universe for some finite years we cannot predict its CREATION and the Created thing is definitely more superior and powerful than us....

There does not have to be a cause. Causality can only exist with reference to time. Since time, along with the other dimensions, only became meaningful once the big bang had occured, cause and effect did not apply.

Causality only really holds on the macroscopic scale anyway. Down at the quantum level, space, time, matter and energy all get smudged together in such a way that causes can indeed precede effects, and particles can arise uncaused from nothingness.

It isn't good practice to ask 'what' created the universe, because you are immediately assuming the existence of a creator or at least a creating force, and therefore eliminating some of the possible explanations before starting.

As for the bigger question of universal origins, I direct you to my answer to this question: http://answers.yahoo.com/question/index;_ylt=Am8AdwkKYMgtFu6KDy9sEx_ty6IX;_ylv=3?qid=20091024083221AAxDfJH&show=7#profile-info-yFzxQpiWaa

Also consider watching this presentation by physicist Lawrence Krauss on the subject:

The Big Bang theory is only an explanation of the expansion of the universe (of space itself) and of what happens to the energy content of the universe as it expands (and cools).

The theory simply takes it for granted that the energy was already present and was already expanding at the "Planck Time" (the moment we call the beginning).

Causality (the name of the principle whereby cause precedes effect) is true.  According to the principle, since the universe is an obvious effect, there must be a cause.  However, the principle does not help us to determine WHAT the cause is.

The problem is that the energy density, at the Planck Time, was so high that we know that matter itself could not have existed then, and that the forces themselves also did not exist.  We do not even understand how time itself can flow through this energy density.  

To put it bluntly, we do not know how to use the word "before" when we apply it to that moment.  And without a clear definition of "before", finding a cause (which must come before) is very difficult.

But, the fact that we do not know what it is, does not mean that there is not a cause.  That is why the principle has not been contradicted.

Since we do not understand how time flows at (and "before") the Planck Time, maybe there was nothing to "cause" whatever came before:  for all we know, the energy had been there (and expanding) for an eternity.

Or it just came out of nowhere, just like virtual particles that are created out of "nothing" by random quantum fluctuations.

Cause and effect may not necessarily be true... see quantum entanglement.

The universe is everything that exists, that we are able to know about. If we knew what caused the big bang or what existed before it, those would also be part of the universe.

No one Knows.
These kinds of questions will only bring more questions.
What caused the Big Bang? Then what created that? What created that? Then what created that?
It'll go on forever.

The cause may be something as simple as a finite potential.
  The potential may be the result of a finite nothing.

Living energy created the universe. This energy has always existed. There is not an understanding how this can be the case, at least not at this point of human intelligence.
