The fact life has been on the planet evolving for close to 4 billion years is a biggie. It’s a fact there was no global covering mega-Flood only 4500 years ago. It’s a fact all extant animal species weren’t bottlenecked down to one or seven breeding pairs in that same 4500 year ago time. Fact doesn’t mean “absolute truth”. It means confirmed to such a high degree it is virtually universally accepted as objective reality. The YEC claim of “same data different interpretation” is about the lamest hand-waving excuse imaginable.
