The 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, is 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.
The evidence supporting Big Bang Cosmology is as solid as the evidence for a heliocentric solar system.
The observation that red shifts of distant galaxies gets greater the further away the galaxies are.
Real scientists do not "gather evidence in support of" any theory. The technical term for that kind of thing is "cherry-picking". Real scientists build a theory to explain the evidence that they have already gathered, and then test the theory to see whether it holds water. The easiest, fastest way to make sure that you are regarded as a wingnut by real scientists is to adopt or invent a theory, and then spend your time trying to prove it.
Two tools used in the Big Bang Theory are the telescope, which is used to observe distant galaxies and study the cosmic microwave background radiation, and the particle accelerator, which is used to recreate high-energy conditions similar to those that existed in the early universe.
Hello i am minakshi and the answer is that the evidence collected by each tool is that the cosmic background microwave radiation sent by cosmic background explorer through radars it suggest that there was big bang in the past as big bang theory supports , the hubble space telescope which gives us information about the red shifs of galaxies and the doplers efect, and the analizationof the presence of light elements hydrogen and helium through spectroscope.
Three important pieces of evidence are:* The redshift of distant galaxies. This means that galaxies are moving away from us. * The percentages of elements and isotopes. This closely matches predictions from theory. * The cosmic background radiation. This, too, closely matches predictions from theory.
The observation that red shifts of distant galaxies gets greater the further away the galaxies are.
The red shift and the cosmic microwave background radiation was the evidence used to develop the big bang theory.
Evidence used to support evolutionary theory includes the fossil record showing the progression of species over time, comparative anatomy and genetics showing shared traits among different species, and the observation of natural selection acting on populations leading to adaptation and speciation.
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.
Theory.
Any items of information acquired through observation or experimentation may be used to either confirm or disprove a scientific theory, or even to suggest a new theory.
A theory is a well-supported explanation for phenomena based on observation, experimentation, and analysis. Data refers to the facts, figures, or information collected from experiments, surveys, or observations, which are used to support or refute a theory. In summary, a theory is an overarching explanation, while data are the specific observations that inform and test that theory.

Louis pasteur was the one to support th theory of biogenesis.
