Evidence for the Big Bang: NASA, Lawrence Krauss, et al., say it's the theory's predictions.* The Big Bang's Failed Predictions and Failures to Predict: (Updated Aug 3, 2017.) As documented below, trust in has been misplaced when compared to the actual astronomical observations that were made, in large part, in hopes of affirming the theory.- Sidney van den Bergh of Canada's National Research Council writes at Cornell's that it is unclear who was responsible for the omission but he reports of the 1931 Monthly Notices "authorized translation of Lemaître's  discovery" that the "mention of the expansion of the Universe was omitted from the English version of both Eqn.[equation #] 24, and from the English text [and that this] suggests that this exclusion by the translator was deliberate..." However, that shocking and historic omission primarily benefitted Hubble and it was only one year earlier that Hubble himself was insisting that he be given full credit (regardless of the truth) for this discovery.For a creationist and a secular explanation of this problem, see creation.com's report on the Discovery Channel's How the Universe Works, and see this Fermilab antimatter video: Yet even secular science authorities have begun objecting to the systematic misattribution, and hence, post-dating, of the the claim of expansion.
Extensive compelling scientific investigation including repeatable experiments suggests that there is an entire cosmos worth of antimatter that should have been created by the big bang within our universe that, thankfully, simply does not exist.
The Corrected History of the Discovery of Expansion: On the entire Internet, the following is the most concise and reasonably comprehensive chronology of the discovery of the (apparent) expansion of the universe.
The Day We Found the Universe, Princeton's cosmologist James Peebles, A Different Approach to Cosmology, Discovering the Expanding Universe, and the proceedings of a conference titled, The Big Bang and Georges Lemaître.
When supercolliders form matter from energy, as expected from the laws of physics, equal parts of matter and antimatter form; and if they come into contact, they annihilate one another.
Big Bang theorists have spent decades looking for antimatter regions of the universe with leading astronomers culminating a significant project by writing in The Astrophysical Journal: "we conclude that a matter-antimatter symmetric universe is empirically excluded." The journal reports a physicist's assessment: "The work is extremely compelling and gives me fresh pessimism" that is, on the difficulty of explaining why the universe even exists.
