No one who knows anything about cosmology alleges that the universe is 4-6 billion years old. The best current figure is 13.7 billion years. Our particular solar system is about 4.5 billion years old.

IF the universe was only 4/6 billion years old we would have no clue what had happened 10 billion years ago because we what ever existed then has been totaly changed by the universes existance. It may be infact that there was another universe that lived and died before ours not that you would be able to tell if it evaporated into nothingness ect... So inshort as far as what scientist say the universe is about 13 billion years old not 4/6 and I wouldnt be suprized if it was actualy much older then that of course there probably was at some point no universe of course I cant say that 4 sure. SO that means nothingness existed before it or something totaly wierd that no one can understand yet :)

As previous posters have said, the Sun and it's planetary satellites are roughly 4.6 billion years old. The Universe, it is estimated, is about 13.5 billion years old.
The reason why the question of "what happened a billion years before the big bang" doesn't really work is because of how intricately time is related to space. Time is all relative (as I'm sure you've heard before). Given the right frame of reference, time can stand still (e.g. if you're traveling near the speed of light, time moves relativistically slower). But because time is all relative, without a physical frame of reference (which didn't exist before the Big Bang) there is no time to speak of.
Since we don't yet have an answer to that question, it still falls into the realm of religion for a great many people. The science to figure out what happened before the Big Bang simply hasn't been created yet.

No..
the Universe is about 13 1/2 billion years old..
The Earth is about 4 1/2 billion years old..

Although the universe is not just 4/6 billion years old, but assuming it is, and the question was of a time before thw beginning of this universe, what happened then is definitely of no known record except that in the beginning there has been One and then there has been Many. It can only be as metaphysical as your question that queries on before or at about the creation Time.

The earth is app. 4.5 billion and the universe is app. 13-14 billion. The M-Theory states that the 11 dimensions coexisted and the collision of two or more membranes caused the "Big Bang" because the energy 'generated' [Law of Conservation of Energy: not created or destroyed] was transformed into matter which now existes in our plane. [E=mc^2]

Please think about this....If I asked you when numbers end, what would be your answer ? It should be that they never do. However, there is a point where numbers lose their practical significance. For instance, it could be of at least theoretical use to calculate the number of sub atomic particles in the universe. Still, there would be a number higher than this. You could abstractly in your mind ALWAYS add one more number, or for that matter one more second of time. In the end, you only need as many numbers as you have things that might need to be counted. The same goes with time. We don't need to know what happened " before time ". If anything did happen "before time", then that- by definition- would not be before time. In essence, there was no time before the universe came into being.....think VERY hard about that !

Wrong. The known universe is 14 billion years old. The earth is 4.6 billion years old.

My belief is that the universe has always been here, all I know is that scientist say the sun is about 4.6 billion years old not the universe, universe has been here much longer.

Time began when the universe began. Asking what occurred before that time doesn't make sense. This happens other times in physics also.
What is faster than the speed of light? What is colder than absolute zero? Just because we can phrase the question doesn't make it meaningful. The questions are meaningless because such things cannot exist.
Knowing what happened before the universe existed doesn't make sense because there was no time before the universe existed.
