It doesn't really explain it as describe it.
Think of the universe as sort of the smoke and debris that resulted from a massive explosion.
Inflation theory. This theory suggests that in the first moments after the Big Bang, the universe underwent a rapid and exponential expansion, causing it to grow exponentially in size. This concept helps explain certain observations of the universe, such as its large-scale structure and uniformity.
There are various concepts and theories about the universe, including the Big Bang theory, multiverse theory, inflation theory, and the cosmic microwave background radiation. These concepts seek to explain the origins, expansion, and composition of the universe.
It is not so much that the universe is expanding, but rather the rationalization for its expansion that provides evidence to support the Big Bang Theory. The Big Bang supports interpreted observational evidence of the Cosmic Microwave Background Radiation (CMBR) barrier that there is an evolutionary expansion of the universe which promotes a finite age for the universe.
Scientists believe the "first event" in the Universe was the Big Bang. The Big Bang Theory attempts to explain how the universe was originally created.
The big bang theory states that the galaxies in the universe are continuously moving away from each other due to the expansion of space. This expansion suggests that the universe began from a hot, dense state approximately 13.8 billion years ago.

The big bang theory explain the creation of everything. It gives the explanation of beginning of our universe and it's evolution
Hello i am minakshi answer is that the big bang theory is an example of old scientific theory as big bang theory explains that there was an explosion but the isotropy and the homogenity of the universe is not explained by big bang theory to explain his we connect inflatation theory with big bang theory to explain it so the big bang theory is also an example of old scientific theory.
Evidence. See related question.
The Big Bang Theory is very well accepted by the scientific community; it is considered to be solidly supported, and it is regarded as the best theory that we presently have, to explain the origin of the universe as we know it.
Why our Universe is composed almost entirely of matter, with almost no anti-matter in it.
Some refer to it as the Great Expansion, because the Universe didn't really "bang", it just began a very rapid expansion.
