Ditch the components and rename the spells to something less goofy than "Fizban's Fantabulous Fatabuliser". A tedious job, but you are probably only going to use a subset of available spells, along with a few new ones.D&D magic doesn't resemble most fictional magic either. And no, it is not any more difficult to explain the spell system with pseudoscientific made-up nonsense than it is with mystical made-up nonsense.
Although it's worth noting that in Starfinder the regular Pathfinder classes still exist, along with their goofily named spells. So "you can't do science fantasy without ditching spells" is a pile of horsesheet.
