So you say. We'll see if that holds. (Spoiler, it doesn't.)
From her other videos I know that she grew up in an evangelical household with lots of exposure to YEC. (Two burdens I never had to bear.) Her video isn't about beliefs or the bible, just the unphysical things YECers make the Earth do so that they can pretend the evidence in the rocks, physics, and their literalist interpretation of Genesis are compatible. (They aren't, and the "heat problem" is just one reason why not.) If you poke around on her channel you could find her arguing with presuppositionalists (a personal weakness she admits to) on livestreams.
If you want to call her a young woman because you are an old, fine, but she is not a minor female (girl). Perhaps you are unfamiliar with higher education, but graduate students already have completed their 4-year college degrees and are typically in their twenties. (She's also married.)
