Much more important to worry about how well the kids understand math, and secondarily, physics (aka applied math!) and/or similarly math-using subjects (accounting, baking, chemistry, economics, programming, etc. etc. etc.) Those subjects are genuinely hard to master, and everyone should understand the basics because they're useful for so many careers.
As you say, learning the basics of evolution is something that can be done on your own in a weekend reading wikipedia. Similarly, you can learn the mainstream scientific explanations of how the universe was created from watching a few youtube videos. That's basically how I learned that stuff as an (atheist) homeschooled kid.
School seems to fail to teach the philosophy of science well anyway - skepticism, evidence, double-blind testing, etc. So I don't think evangelical homeschoolers are missing that much.
