The best theory is that all matter was created at the Big Bang
It is what created the universe
There are various scientific theories about the origins of matter, but the Big Bang theory is the most widely accepted explanation for the early moments of the universe. If the Big Bang theory were to be proven false, it would require a new, evidence-based theory to explain the creation of matter. However, as of now, the Big Bang theory remains the prevailing scientific understanding of the universe's origins.
You are giving the definition for the Big Bang Theory.
The universe was created roughly 13.7 billion years ago. The most widely accepted scenario for the creation of the universe is known as the big bang theory. In lay man's terms, the theory says that the universe was created through a rapid expansion of time and space that still continues today as the universe expands.
The best theory is that all matter was created at the Big Bang
According to the big bang theory the universe began about?
The matter that existed since the Big Bang is expanding. A few decades ago, a "steady-state" theory was popular; according to it, matter was created as the Universe expanded, thus maintaining the matter density in the Universe constant. However, observational evidence did not support this theory.The matter that existed since the Big Bang is expanding.

Friedmann Universe Theory was created in 1922.
Pulsating Theory According to this theory, the universe is supposed to be expanding and contracting alternately i.e. pulsating. At present, the universe is expanding. According to pulsating theory, it is possible that at a certain time, the expansion of the universe may be stopped by the gravitational pull and the may contract again. After it has been contracted to a certain size, explosion again occurs and the universe will start expanding. The alternate expansion and contraction of the universe give rise to pulsating universe.
The steady state model assumes that new matter is created at the universe expands, the big bang theory states that no new matter is ever created, but only changes form.
The Big Bang theory proposes that the universe began as a singularity and expanded rapidly about 13.8 billion years ago, spawning matter and energy. The steady-state theory suggests that the universe has always existed and undergoes continuous creation of matter to maintain a constant density. The inflation theory posits a period of rapid expansion immediately after the Big Bang, leading to the universe's current structure.
That is a theory that, while the Universe expands, new matter is created (at a very slow rate); the final result is that the Universe looks the same today as in the past. This is an alternative to the Big Bang theory (while acknowledging the expansion of the Universe); however, it contradicts more recent observations. In the past, the Universe was indeed quite different from today.
When the big bang theory started the universe, light was created.

The big bang all the matter of the universe was compacted in a very small thingy and then it exploded and we have the universe
