Which civilization? The U.S.? That might slow science down, but it would not significantly reverse progress on it. Of course nations/kingdoms/empires/civilizations wax and wane, but you can't use the word "too" if you're talking about a total worldwide collapse of human civilization as a single event -- such a thing has never happened. If your point is that a Chicxulub or a worst-case Wyoming Supervolcano could outmatch the progress that science has made, then: sure, what's your point? The vast majority of established science will outlive mere nations and petty politics. There are too many copies of Wikipedia, too many printed textbooks and encyclopedias, to lose a significant portion of established science. The possibility of worldwide humanity-destroying events does not disprove this at all. In fact, if we ever faced a humanity-destroying event, then it would be nothing less than our collective scientific progress that would have any chance of seeing us through it.
