It is a theory that the universe started from a "big bang." This is considered by scientists as the earliest recorded history of the universe. It is believed that the entire universe was so dense it was possible that it could have been the size of a planet or smaller. All that density was too much and it exploded. Everything back then was hydrogen. The hydrogen formed into stars. The stars created other elements because of the neclear reactions breaking up the hydrogen and connecting it together. This led to planets. Unfortionatly I would say there is too much info to share everything. Try reading :

There are theories, but you know what they change all the time. Hundreds of years ago, it was that god created it. Then there was the steady state theory, and then there is the big bang theory, then I don't know. I am pretty sure we will have some other or a modified big bang theory sooner or later. So I don't think it really matters, you can never be 100 % sure that this is how it happened, there is always some room for error.

some scientists said that first there was a small dot like thing in which the universe was condensed and when the big bang occur ed everything got spread all around and the universe began to expand. it is expanding continuously.

There are physical processes we can observe in the universe as it changes and "evolves", but I believe the origin lies in the wise and loving creation of God. And we see what He is like by looking at Jesus.

Based on measurements of the expansion of the universe using Type 1a supernovae, measurements of the lumpiness of the cosmic microwave background, and measurements of the correlation function of galaxies, the universe has a calculated age of 13.7 ± 0.2 billion years. The agreement of these three independent measurements is considered strong evidence for the so-called ÎCDM model that describes the detailed nature of the contents of the universe.
The early universe was filled homogeneously and isotropically with an incredibly high energy density and concomitantly huge temperatures and pressures. It expanded and cooled, going through phase transitions analogous to the condensation of steam or freezing of water as it cools, but related to elementary particles.
Approximately 10-35 seconds after the Planck epoch a phase transition caused the universe to experience exponential growth during a period called cosmic inflation. After inflation stopped, the material components of the universe were in the form of a quark-gluon plasma (also including all other particles—and perhaps experimentally produced recently as a quark-gluon liquid [3]) in which the constituent particles were all moving relativistically. As the universe continued growing in size, the temperature dropped. At a certain temperature, by an as-yet-unknown transition called baryogenesis, the quarks and gluons combined into baryons such as protons and neutrons, somehow producing the observed asymmetry between matter and antimatter. Still lower temperatures led to further symmetry breaking phase transitions that put the forces of physics and elementary particles into their present form. Later, some protons and neutrons combined to form the universe's deuterium and helium nuclei in a process called Big Bang nucleosynthesis. As the universe cooled, matter gradually stopped moving relativistically and its rest mass energy density came to gravitationally dominate that of radiation. After about 300,000 years the electrons and nuclei combined into atoms (mostly hydrogen); hence the radiation decoupled from matter and continued through space largely unimpeded. This relic radiation is the cosmic microwave background.
Over time, the slightly denser regions of the nearly uniformly distributed matter gravitationally attracted nearby matter and thus grew even denser, forming gas clouds, stars, galaxies, and the other astronomical structures observable today. The details of this process depend on the amount and type of matter in the universe. The three possible types are known as cold dark matter, hot dark matter, and baryonic matter. The best measurements available (from WMAP) show that the dominant form of matter in the universe is cold dark matter. The other two types of matter make up less than 20% of the matter in the universe.
The universe today appears to be dominated by a mysterious form of energy known as dark energy. Approximately 70% of the total energy density of today's universe is in this form. This component of the universe's composition is revealed by its property of causing the expansion of the universe to deviate from a linear velocity-distance relationship by causing spacetime to expand faster than expected at very large distances. Dark energy in its simplest formation takes the form of a cosmological constant term in Einstein's field equations of general relativity, but its composition is unknown and, more generally, the details of its equation of state and relationship with the standard model of particle physics continue to be investigated both observationally and theoretically.
All these observations are encapsulated in the ÎCDM model of cosmology, which is a mathematical model of the Big Bang with six free parameters. Mysteries appear as one looks closer to the beginning, when particle energies were higher than can yet be studied by experiment. There is no compelling physical model for the first 10-33 seconds of the universe, before the phase transition that grand unification theory predicts. At the "first instant", Einstein's theory of gravitation predicts a gravitational singularity where densities become infinite. To resolve this paradox, a theory of quantum gravitation is needed. Understanding this period of the history of the universe is one of the greatest unsolved problems in physics

God...or the Creator if you prefer...I don't know who else or what else can create time and space out of nothing. Before the universe was created there was no matter, no time and there was no space.

well, people say that trillions of trillion years ao, two molecules or atoms collapsed and caused the big bang, the formation of planets and air and molecules occured.
