The Astroparticle Physics Laboratory conducts research at the interface between cosmology and high-energy particle physics to investigate the birth and evolution of the Universe in terms of unified theories of fundamental interactions.

Nothing existed before the big bang.
Outlined below are some of the major theories that have surfaced in the scientific community, describing the creation of the universe, and/or describing what happened before the big bang. Perhaps God had many choices when creating the universe.
The Bouncing Universe
In the 1960's, a physicist named John Wheeler developed the bouncing universe theory. The theory's premise involved having a universe come into being with a bug bang, expand for a while, and then implode at a certain point in time. Upon reaching reaching a certain small size (maybe even a singularity), that universe may "bounce" and re-explode in a new big bang. As a result, the universe follows a cyclical pattern of expansions and contractions.
The Protouniverse
This theory involves the formation of matter from nothingness before the explosion of the big bang. It is related to the white hole theory. A white hole is a theoretical opposite of a black hole, wherein matter would continuously appear at the speed of light, as if from nowhere. Although there is believed to be no observational evidence of white holes, the protouniverse theory was created in an attempt to explain the non-uniformity and the varying density of the universe.
The Inflationary Theory
In 1981, a particle physicist named Alan Guth created a new theory. Guth knew about the matter in physics that explained how elementary particles got their mass. This matter is called scalar field matter. Combining the mathematical equations for scalar field with Einstein's equations describing the expansion of the universe, Guth developed a theory in which large amounts of matter and energy were created from nothing! After matter and energy were created, the universe experienced an accelerated expansion, becoming exponentially large prior to continuing its evolution according to the big bang model. This theory has been worked on and modified by many cosmologists since its introduction.
The Bubble Universe / Andre Linde's Self Creating Universe
These are the theories discussed in class. The bubble universe concept involves creation of universes from the quantum foam of a "parent universe." On very small scales, the foam is frothing due to energy fluctuations. These fluctuations may create tiny bubbles and wormholes. If the energy fluctuation is not very large, a tiny bubble universe may form, experience some expansion like an inflating balloon, and then contract and disappear from existence. However, if the energy fluctuation is greater than a particular critical value, a tiny bubble universe forms from the parent universe, experiences long-term expansion, and allows matter and large-scale galactic structures to form.
The "self-creating" in Andre Linde's self-creating universe theory stems from the concept that each bubble or inflationary universe will sprout other bubble universes, which in turn, sprout more bubble universes. The universe we live in has a set of physical constants that seem tailor-made for the evolution of living things.
The Hawking-Turok Instanton Theory
To provide you with a different perspective on how the universe may have been created and what may have happened before the big bang, the Hawking-Turok model is discussed in this set of web pages. In essence, the Hawking-Turok model suggests that there was a spontaneous creation of an open, inflationary bubble universe from nothingness.

If you have a bible i will like you to please read the account of Genesis 1:1-31 if you can and you will find the answer to your question..Creation according to Genesis refers to the creation of the heavens and the earth by the God of Israel as depicted in Genesis, the first book of the Pentateuch (as well as of the Hebrew and Christian Bible). The text spans chapters 1 and 2 of the book of Genesis and was written in the Hebrew language.
The Genesis creation accounts have long been the subject of debate among scholars on several fronts; the most hotly debated issues relate to authorship, textual criticism (specifically, whether there is a single or dual account), and interpretation of the text (in light of scientific analysis of age of the Earth and the theory of evolution).
Today, most prominent “Christian” religious groups seem willing to accept that God must have used evolution in some way to create life. Some teach that God preprogrammed the universe to develop in such a way that living things inevitably evolved from lifeless chemicals and eventually produced mankind. Those who subscribe to this teaching, known as theistic evolution, do not feel that God interfered with the process once it started. Others think that, in general, God allowed evolution to produce most families of plants and animals but occasionally stepped in to move the process along.

The short answer is that the best working model for the formation of the universe is known as the Big Bang theory. You can look it up here: http://simple.wikipedia.org/wiki/Big_Bang
I am a Christian and I believe in both God the creator and the Big Bang. Not all who believe in God are wackos.

No-one knows, and no-one ever will. Think about it: even if we could figure out what the initial conditions were that led to the Big Bang, we would then have to ask what led to these conditions. And even if we could somehow figure that out, we still wouldn't know what came before *that*, etc., etc. It will always be an endless puzzle. The Universe just exists, and we will never, ever know the real reason why.

they say it was made by a black whole it started small and tiny tiny tiny tiny tiny micro scoufic particals formed the atmesphere and by millions of the years the earth broke down some of the particals and outer viruses and formed the earth at leats thats what the NASA nerds say.
