"Spacetime" also does not exist. Time doesn't exist as a force of nature or tangible entity, it's nothing more than a subjective measurement. It exists like your height measurement exists, or the measurement of four meters of distance from you to the wall exists. The matter contained in the space of distance being measured exists, and the events between (subjective) time measurements existed, time itself does not exist. You can measure your height from the ceiling to your head (impractical but you can do it). You can measure time based on Mars going around the Sun. Neither entity exists (your height, nor time; both are subjective based on the anchor chosen). It would be silly to think height measurements are a tangible force of nature, we'll call it HeightSpace, now we must discover how it rules over the universe and seek to observe its magic principles.

The bogus nature of "spacetime" has held back multiple fields for many decades. It has wasted a generation of brains that fell for it.
