Actually I think, that spherical coordinates make more sense than Euclidean.

The idea behind Euiclidean geometry is what Newton called 'absolute space'.

I personally regard this concept as wrong.

I would like to take spacetime of GR as 'prior' and regard our 'space' 
as a mere optical illusion.

The universe as we see it, is actually stacked in time, hence is not 
real, but a picture.

We receive this picture by means of light, hence all seen events belong 
to our own past light cone.

https://en.wikipedia.org/wiki/Light_cone

Since the vertical axis means time, we have a set of circles, which are 
'stacked in time'.

And since these circles are two-dimensional reductions of three 
dimensions, we have actually nested spheres.

These set of nested spheres are similar to Ptolomy and his crystal 
spheres, because the spheres are representations of time (meaning: the 
further away the longer ago).

Now Euclidean geometry does not fit to this picture, because Euclidean 
space is timeless, while spheric geometry would.
