The facts that provide evidence that the space within our Universe was almost infinitely dense about 13.7 billion years ago, and has been expanding at a (pretty much) steady rate ever since, are overwhelmingly persuasive.
1) The distance between us and all distant galaxies is increasing, and the rate at which that distance is increasing is directly proportional to the distance to those distant galaxies.
2) The existence, spectrum, and isotropy of the cosmic microwave background radiation.
3) The ratio of hydrogen to helium in all parts of our Universe.
4) Quasars are seen far from us, but not close to us.
5) The ratio of long-lived isotopes to their decay products.
6) The absence of white dwarf stars older than about ten billion years.
These facts make Big Bang Cosmology as solid an idea as a heliocentric solar system.
Scientists believe that the cosmic microwave background radiation (CMB) provides compelling evidence for the Big Bang theory. This faint glow of radiation, uniformly detected across the universe, is a remnant of the hot, dense state of the early universe approximately 380,000 years after the Big Bang. Additionally, the observed redshift of distant galaxies supports the idea of an expanding universe, consistent with the predictions of the Big Bang model. Together, these observations bolster our understanding of the universe's origins and evolution.
Scientists point to the Cosmic Microwave Background Radiation (CMB) as a key piece of evidence for the Big Bang theory. This faint glow of radiation, uniformly detected across the universe, is thought to be the remnants of heat from the early universe, approximately 380,000 years after the Big Bang. Additionally, the observed redshift of distant galaxies indicates that the universe is expanding, further supporting the idea of an initial explosive event. Together, these observations reinforce the understanding of the universe's origins as described by the Big Bang theory.
Scientists point to the cosmic microwave background radiation (CMB) as a key piece of evidence supporting the Big Bang theory. This faint glow, uniformly detected across the universe, is thought to be the remnant heat from the hot, dense state of the early universe, now cooled and stretched as the universe expanded. Additionally, the observed redshift of distant galaxies indicates that the universe is expanding, consistent with Big Bang predictions. These observations collectively reinforce the idea that the universe originated from a singular explosive event.
The theory is based on replicable evidence. This evidence turns a theory into a fact.
The Big Bang Theory is a widly accepted theory in the scientific world because of the fact that it has less loopholes than others made to oppose it.I believe 1-2 loopholes are contained in The Big Bang Theory.

They didn't; the big bang theory is just an idea or a theory, not a fact. The empirical evidence that our Universe was, 13.7 billion years ago, much more dense that it is now, is overwhelming. No other explanation even begins to explain what we observe in our Universe. Saying the Big Bang is a "just an idea or theory" is like saying gravity is "just an idea or a theory, not a fact."
The fact that the universe is expanding is a key piece of evidence for the Big Bang theory. Observable redshift of distant galaxies, cosmic microwave background radiation, and the abundance of light elements like helium and hydrogen all support the idea that the universe began in a hot, dense state and has been expanding ever since.

The Big bang theory states that the galaxies are in fact moving away from each other

The redshift of distant galaxies, which is normally attributed to the Doppler effect.=========================Comment #1:It's important to include in the answer the fact that the question speaks ofhow science is NOT done. Evidence is not used to support theory. Theoryis the attempt to explain existing evidence. THAT's how science works.
The discovery of cosmic microwave background radiation is a key piece of evidence for the Big Bang Theory. This radiation is a faint glow found throughout the universe, believed to be leftover from the intense heat of the Big Bang. Its characteristics match what would be expected if the universe started as a hot, dense state and expanded over time.
The theory is based on replicable evidence. This evidence turns a theory into a fact.
Antonyms of theory include fact, reality, evidence, and truth.
A hypothesis is a statement of theory. Something that is unproven. You gather evidence to support that theory. Gather enough evidence to support and a theory becomes accepted as fact.
A theory becomes a fact when that theory is supported by experimental evidence.
