That's because science requires evidence and being repeatable. Creationism is some BS created to justify a conclusion.
That's the problem with using a religious text as a objective truth. You have to continuously invent a bunch of nonsense to explain it away.
Science says life has been evolving on this planet for millions of years. Creationism says that nope, it's only 6000 years AND there's been an extinction level event where only some were saved. Also, only 8 people survived.
which, I dunno if you've done that math, but that would mean the 8 people population would have to double every year. Which means the 4 women would have to give birth twice in 1 year. And those babies would have to be born full adults to also give birth... and so on... for 4,000+ years.
We would have seen that.
Also, that wouldn't leave time for people to migrate across the globe and establish different cultures that also had 1,000s of years of easy documentation existence.
That's how you know creationism is a bunch of bunk. Because when you stop to think about it, and work through how it could happen like that, it becomes obvious it couldn't.
Teh guy who told you he'd reduce inflation, cut gas prices in half, never start a war, and deliver a healthcare plan has driven inflation up, gas prices have doubled, started a war for no reason and no clear objectives, and took away healthcare for people on medicare and medicaid.
