It is remarkable how you can be so wilfully ignorant.
Evolution is biology, so biologists don't require to give evidences for the Big Bang cosmology.
The Big Bang is about physical cosmology of the universe, and relate to particle physics, general relativity, astrophysics and astronomy.
The Big Bang tried to explain the earlier epoch of very young universe, on how energies and subatomic particles formed the lightest elements first - hydrogen and helium.
Examples of the earlier BB epochs are,
- the Baryogenesis,
- the Quark epoch,
- the Hadron epoch (how protons and neutrons were formed from quarks),
- the Nucleosyntheis epoch (how the atomic nuclei bound and encased protons and neutrons together into ionised atoms (no neutrons in hydrogen ion),
- and the Recombination epoch (how ionised hydrogen and ionised helium atoms become stable and electrical neutral atoms, when electrons are bound to them).
All of the above stages of the Big Bang, are explanation of formation of the earliest elements (hydrogen and helium) BEFORE the formation of the first generation of stars (known as "Population III stars").
The Big Bang Nucleosynthesis (BBN) started at 3 minutes after the Big Bang, and ended at 20 minutes after BB.
The Recombination epoch started 377,000 years after the Big Bang. As I wrote earlier, this epoch explains HOW ionised atoms become electrically stable atoms when free electrons attached themselves to positive-charged elements. This attachment caused photons to decouple from the atoms, releasing in form of earliest light that can be observed from the telescopes (first observed in 1964, but predicted in 1948 by Ralph Alpher and robert Herman), which we called the
Cosmic Microwave Background (CMB) radiation, see image from WMAP (NASA), below:
The CMB radiation is one of the evidences for the Big Bang cosmology. CMBR is the earliest observable light, older than the quasars, older than the first stars.
Before the stars, the most abundant elements in the universe, was hydrogen the lightest element.
These hydrogen began to coalesce together by gravity, until they became massive spheres. As the core (made of hydrogen) became more dense, it reached critical mass and critical temperature causing the first nuclear fusion - fusion of two hydrogen atoms into helium atom.
This process of lighter elements (hydrogen) created into heavier elements (helium) is called Stellar Nucleosynthesis. The nuclear fusion release a lot of radiations, including light and heat.
The whole process that I just described, is how the first star formed.
Eventually stars will run out of hydrogen fuel to fuse together, so it will begin to fuse helium atoms into heavier elements, like nitrogen, oxygen, carbon. At this point, the stars begin to die.
Depending on how massive stars were before it run out of hydrogen.
A star like our Sun, will turned into a red giant star, growing larger in size, before the outer layer of the star are stripped away as debris, leaving only the star's core, becoming a white dwarf star. Our sun (A) will never explode like the supernova, or (B) become a black hole, because the sun is not massive enough star.
The debris from the Red Giant or from the supernova is what create planets, asteroids and other objects in space.
In all this, life has not yet be created yet. The Big Bang cosmology never talk of evolution. And no biologists will ever try to provide evidences for the Big Bang, because evolution is not astrophysics.
Your comment about evolutionists and BB is nothing more than straw man, which you keep repeating again and again, which make you a dishonest and biased creationist - the one who refuses to learn from his mistakes.
A good place to start reading about the Big Bang, which covered briefly on the subject of the WMAP discoveries, can be found here:
If you want some more detail, then the Wikipedia is free, and it has the epochs that I didn't mention in my post:
The Wikipedia have separate articles on the
Big Bang Nucleosynthesis,
Recombination epoch,
Cosmic Microwave Background Radiation (CMBR), etc, which should explain more details.
