As we all know, everything that exists ( i.e can be seen, felt ) has 3 dimensions, but can anything exist for no time? No. That means time is the fourth dimension as nothing can exist for no time!!!

time is usually refered to as the (3 + 1)th dimension...

No – time is not the forth dimension – at least not if you are agreeing to the first three dimensions. Here's why…
First dimension: A straight line
Second dimension: a straight line with another straight line at 90°, again, and again to make a square.
Third Dimension: A square at 90° to the original square, and so on until you create a cube.
Fourth dimension: This is called a "hypercube." To continue with the pattern created by the first three dimensions, you would create cubes at right angles to the original cube until you had a cube in the exact center of the original cube – with all angles being 90°. Obviously, we cannot create this or even really imagine it. If you place a connected cube within a cube, the corners are connected by lines that are at 45°. However, it is possible to project the image into two dimension using a clear plastic cube with another clear plastic tube inside of it – the connecting 45° angles will then 'appear' to be 90°. Voila!
Hawking and Sagan both have more complex explanations, if you wish to pursue them.

The concept of a fourth dimension is one that is often described in considering its physical implications; that is, we know that in three dimensions, we have dimensions of length (or depth), width, and height. The fourth dimension is orthogonal to the other three spatial dimensions. The cardinal directions in the three known dimensions are called up/down (altitude), north/south (longitude), and east/west (latitude). When speaking of the fourth dimension, an additional pair of terms is needed. Attested terms include ana/kata (sometimes called spissitude or spassitude), vinn/vout (used by Rudy Rucker), and upsilon/delta.
The fourth dimension is often identified with time, and as such is used to explain space-time in Einstein's theories of special relativity and general relativity. In this case, the concept of an additional spatial dimension would be referred to as the fifth dimension. In this article, however, we discuss the implications of considering the fourth dimension as another spatial dimension.

Actually the thing which do not exist can be called to be existing for no time !!!!!!!!!!!
Still time is 4th Dimension

time is called the fourth dimension. where have you been?

yes, we can call it the fourth dimension.

time is a mere bi product of gravity and matter.
we perceive time as significant, because we exist for a finite amount of time, while the universe SEEMS to naturally exist without regard to time.

Yes, I think some engineering students even have to do some equations with that theory.

I would say yes. I belive that it is not totaly understood.

Yes, it can and it is. Your analysis is correct.
