By what definition? I've never heard space defined like that. If space is a synonym for the word "nothing", how is it that there are several mutually inconsistent models of space -- flat, spherical, and so on? There's only one type of nothing. How is it that space warps in general relativity? You can't bend "nothing". When I ask my friend "what's colder than absolute zero" and my friend replies "nothing", are they telling me that space is colder than absolute zero? Certainly not. It appears to me that the definition you provide is clearly not correct.

While we're on the subject of definitions, can you give me a few examples of things which you do consider to exist? My tentative guess would be solid objects, atoms, and so on. If so I'm curious as to why these things differ from space in their entitlement to "existing" status. How are you defining "exists"?

Like it or not, there is no such thing as space: it has no mass, no energy, no physical presence at all

It has extension and volume. These can be measured in metres. Energy presupposes the existence of space for its definition, and has a unit of Newton*metre.
