This is an area of active research. In other words, it isn't really known. One hypothesis is that within a larger "something", different universes have formed, with different physical laws and even different numbers of "active" dimensions (see below). In this case, we simply happen to live in one that has three dimensions.
Active dimensions: There is some evidence that our Universe actually has 10 or 11 dimensions, but that only 4 of these (1 time dimension, 3 space dimensions) manifest themselves on larger scales. The other 6 or 7 spacial dimensions are believed to exist only at extremely small scales - much smaller than can be directly observed.
No, the X-wing from Star Wars could not fly in real life because it is a fictional spacecraft with technology that does not exist in the real world.
dimension
Real objects are physical entities that exist in the observable world. They can be touched, seen, heard, smelled, or tasted. Examples include tables, chairs, books, and cars.
The fourth dimension is not "time'. The fourth dimension is a real space dimension r=ct, where c is the speed of light and the fourth dimension r is the product of 'c' and time which gives a real number distance. The other three dimensions are vector dimensions V= Ix + Jx + Ky. The vectors I, J and K are unit vectors with the vector property I2=J2=K2=IJK= - 1. So, all the dimensions are units of space!
"Exist" means to have actual being or to be real. "Excist" is not a recognized English word and does not have a specific meaning. It may be a misspelling or a typo.
There is no such thing as a "fifth dimension" in the real world. Our world, basically, has 3 (spatial) dimensions.
Plato argues that the existence of universal ideas in human minds demands the existence of a supramundane world of pure essences that are stable, real, and eternal. These Ideas exist as real entities apart from the world of sense. Plato argues that Universals are real and that they exist in another dimension of reality.
no may be it doesnt exist coz it it really exist than there must be a crownd around that place
yes they do exist even in the real world they exist.
no it isnt real. if it was real, you think they would sell it for 20$ ? and it doesnt exist in reality.

Pokemon don't exist in the real world.
A fjord is a real world example of a fjord! They exist in the real world.
They exist in the real world: they are physical things.
a pearphone. it doesnt exist in real life tho
of course not, but you can find similar things in the real world
