There must be a substance that exists, which warps in the presence of mass.
You cannot deny this.

Einstein said the "new aether" of relativity has "no substance", and I haven't found any reason to disagree with him, so far. What evidence do you have as proof of a "substance"?

There's a theory about particles called gravitons, but they are only a hypothesis at this point. Even if they exist, they are thought to be likely massless, so would you call something that's "massless" a "substance"?

Challenge accepted. I deny it. There is no substance. Empty space is not flat, and is less so in the presence of mass.
Euclid is for beginners. Learn math, join us, brother.

The sun is moving. The earth is following the sun. What physical occurrence causes the earth to follow the sun? What are the minimal ingredients to the recipe you need, I will start you off;
1. the sun
2. the earth

3. bent geodesics that cause the Earth to accelerate toward the Sun. Through empty space. That's free of "aether".

How do you explain empty space having geodesics?

If you want to say, the total aether does not move, the earth moves, and the meteorite moves towards the earth, but the total aether is stationary in relation to these bodies movements

How do you explain empty space having geodesics?
"In mathematics, particularly differential geometry, a geodesic (/ˌdʒiːɵˈdiːzɨk/ JEE-o-DEE-zik or /ˌdʒiːɵˈdɛsɨk/ JEE-o-DES-ik) is a generalization of the notion of a "straight line" to "curved spaces". In the presence of an affine connection, a geodesic is defined to be a curve whose tangent vectors remain parallel if they are transported along it. If this connection is the Levi-Civita connection induced by a Riemannian metric, then the geodesics are (locally) the shortest path between points in the space."
"Certain types of world lines are called geodesics of the spacetime – straight lines in the case of Minkowski space and their closest equivalent in the curved spacetime of general relativity. In the case of purely time-like paths, geodesics are (locally) the paths of greatest separation (spacetime interval) as measured along the path between two events, whereas in Euclidean space and Riemannian manifolds, geodesics are paths of shortest distance between two points.[4][5] The concept of geodesics becomes central in general relativity, since geodesic motion may be thought of as "pure motion" (inertial motion) in spacetime, that is, free from any external influences."
You have to pick the definition that applies to spaces, not maps.

You're right, there is only one truth, and that is that there is no aether, and thus it doesn't matter if it moves or no.
The only reason you so desperately want there to be one is that you can't visualize an empty space properly.
Yes, there can be empty space that has extent and duration. It's just empty. Vacuum. Void. Nothingness. Yet it occupies volume and has duration. It's easy if you try. There doesn't have to be an "aether" filling it so that you don't have this personal issue with not being able to conceive of a void.
Bravo. Its filled with time and dark matter coupled together

If pure empty space, has the potential to intrinsically be altered of itself in anyway, it was not and never was pure empty space. You lose. I win.
