General Relativity deals with curvature of Spacetime, not just curvature of Space. You can't ignore time because clocks are affected throughout the universe. Spacetime events are what we measure and are independent of observers.
Now, let's come to point: You're asking why we're able to measure effects of Spacetime curvature with classical way when reference ...

I don't understand why we are able to see and measure curvature /
warping of space at all.
The Earth's surface is curved and this can be observed via the vast number of pictures of the Earth from space that now exist.
However, the surface curvature can also be "seen" via measurements on the surface itself.
For example, if one were start at the North ...

Curvature affects how objects in the universe move and interact with one another, and these effects can be measured.
Take, for example, the phenomenon of gravitational lensing. Because spacetime curvature can deflect the path of light, we can potentially observe light coming from objects that are directly behind other objects. Here's a nice picture.
As ...
