Comment on 4th dimension doesn't exist because even 1D or 2D themselves are not real.

Ok. Hear me out.

We draw a line on a sheet of paper. That line only has x and y dimensions mathematically.

BUT

That line is a thin layer of ink. It is on a paper which has a width (however small it be). To explain 2 dimensions we abstracted the whole thing as 2D when in fact it is 3D.

There are no dimensions, there are just mathematical abstractions which helps us think. But there is no proof of a physical object in 1D or 2D.
