From Creation Ministries International:

“Cosmology is a weak form of science, at best. It relies heavily on statistical arguments and on observations that have many possible interpretations. …

…Another problem here is that the big bang is now a paradigm. It is believed to be true–that the universe started that way–so evidence found that contradicts it is woven into the established fabric by use of additional ad hoc hypotheses and new parameters. These result in unknowns that are used to explain the unknown.” – John G. Hartnett
