If there wasn’t a literal Adam and Eve, then Adam and Eve never sinned by eating fruit from the wrong tree, and thus they never passed that sin down to all of humanity, meaning we aren’t all born with “original sin” for which we need to be forgiven and saved from being sent to hell when we die.
It's also kind of a boring question because there's no experiment we could run to explain how creation miracles worked. It's definitely a fountain of controversy, though.
Almost everyone isn't going to do a deep dive into how it all works/become professionals in that area, so even the science is effectively just a story for them. If parents want to tell their kids a different story, it doesn't really matter much. Public school k-12 science is so basic that as has been said elsewhere in the comments, you can learn it all from Wikipedia in a few days anyway. The important topics are reading, writing, and math/logic. Ideally history and political philosophy, but it's not clear that schools meaningfully teach that anyway.
