"The period before the big bang could not of existed before the big bang,
this is because there really was nothingness before the big bang
The period before the big bang was only created at exactly the same time the big bang was,
As the big bang WAS the START of everything, It means that there cannot of been anything before the start itself,
The 'nothingness' before the big bang was created at exactly the same point as the big bang
created our universe,
due to time being created (this is how & why there CAN be possible alternative universes) that instantly then created a period BEFORE the big bang,
As before time itself was created, there was just a stillness, (stillness is non-movement, non-force)"
time is disruptive of the stillness, like ripples in a pond,
each new ripple would then be an 'alternate universe',
so once the big bang happened and time was created, the period before the big bang was then also created and is the start of the first ripple of time,
Meaning that something really can and probably did come from nothing
If parallel universes exist, can they collide?

Michio: "Probably. The latest cosmological data comes from the WMAP satellite currently orbiting the earth. The data is consistent with “inflation,” i.e. the idea that the universe began in a super turbo-charged expansion at the instant of the big bang. However, inflation is also a quantum theory, i.e. there is a finite probability that if inflation happened once, it can happen again, and again. In fact, big bangs may be happening all the time, even as you read this sentence. There may be a continual creation of universes.
In other words, our universe is probably a bubble of some sort which is expanding. But inflation theory seems to indicate that we may not be the only bubble/universe. Think of a bubble bath, in which there are innumerable soap bubbles floating, sometimes colliding, sometimes breaking in half, sometimes popping in and out of existence. This is the “multiverse” picture which seems to be emerging from inflation theory.
Inflation theory, however, cannot explain the dynamics of these bubble/universes. Inflation simply states that such a turbo-charged expansion took place, but inflation does not explain why inflation took place in the first place, or what drives it. For that, we need a higher theory, such as string theory (or its latest version, M-theory, where M stands for membrane).
In M-theory, there are innumerable membranes floating in a much larger arena (11 dimensional hyperspace). We live on the skin of one such bubble which lives in 3 dimensional space. However, there may be other “branes” floating in 11 dimensional hyperspace. The physicists at Princeton calculated what would happen if two such branes collided. Much to their surprise, they found that the two branes would merge and create a shock wave. By analyzing this shock wave, they found that it resembled the big bang itself. In fact, they were led to believe that this WAS the big bang. This theory is now called the Big Splat theory, and is one of the serious candidates for the underlying big bang theory."
Universe may have been created with Big Splat
“One new discussion that has arisen from their studies, which was stated in the ScienceNOW Daily News article “No Dice for Slow Roll?” (December 21, 2007), states, “Although the findings don't rule out traditional inflation theories, they do open the door for other theories about how the universe began, including the idea that the universe began with a splat rather than a bang.”

If there was nothingness before the big bang then how can something be made from nothing? That is like saying us and our societies came from no where. There had to be something in order to create the particles, atoms and molecules to create the big bang or else we should not even exist.
Cosmologists Paul Steinhardt and Neil Turok have a radical idea that could wipe away these mysteries. They theorize that the cosmos was never compacted into a single point and did not spring forth in a violent instant. Instead, the universe as we know it is a small cross section of a much grander universe whose true magnitude is hidden in dimensions we cannot perceive. What we think of as the Big Bang, they contend, was the result of a collision between our three-dimensional world and another three-dimensional world less than the width of a proton away from ours—right next to us, and yet displaced in a way that renders it invisible. Moreover, they say the Big Bang is just the latest in a cycle of cosmic collisions stretching infinitely into the past and into the future. Each collision creates the universe anew. The 13.7-billion-year history of our cosmos is just a moment in this endless expanse of time.

I believe standard cosmology is in agreement with the OP thus far: Time and space did not exist before the Big Bang.
You protest, 'But how can something come out of nothing? There must have been something there before!' But there was no before. Therefore there wasn't any something.
The Big Bang was the Beginning.
