hi CD if you are saying they are treating theories as fact, then they are wrong. a theory is just that........a theory only untill proven beyond doubt then its fact. at present we can only theorise at the big bang (as no one was there to wittiness it). at present the big bang theory 99.9% fits into what astronomers are observing, BUT its the 0.1% that stops the theory from being fact. at present astronomers have a "working theory" the best so far, that is untill a better theory comes along to replace the old one.
