A singularity is a region at the centre of the black holes. Not much is known about it.It even traps light.Anything that is attracted in a black holes is present here.A person sucked into a black holes will have a painful death

if you tell me how we got to know about its EXISTENCE

“We” (science) do not know that. A “singularity” — in the scientific sense of the term — is not some kind of object, it is only a fancy name invented in order to avoid saying “we don’t know what’s happening in such a place, or if it even exists.” More often than not, it is a euphemism for division by zero, as in two cases that are repeated ad nauseam:
(1) The “initial singularity” (before the “big bang”): Here, cosmologists are making the assumption that — because they have interpreted galactic redshift observations to be evidence for “space expansion,” the Universe volume must have been smaller in the past — as they extrapolate “back in time,” and as the energy/mass content must have stayed the same (conservation laws), the Universe density must keep rising as we approach the “bang.”
The equation is very simple: Universe density ρUU = mUU/VUU, where mUU = Universe mass (energy), and VUU = Universe volume.
When VUU = 0, the equation no longer represents valid math, but rather than admitting that science does not know/understand how such a situation can be physically allowed to happen, science flat out lies, and declares that “density becomes infinite” (as they say temperature does, BTW, and for the same reason). Why is this wrong? Because infinity is not a number.
(2) The “gravitational singularity” at the center of a “black hole”: Here, cosmologists and astrophysicists are making the assumption that it is possible (“because Einstein’s equations tell us itmust be so”) for any mass to be compressed into oblivion (nothingness), if only sufficient pressure is applied.
Again extrapolating, at the point where the radius of the gravitationally collapsing body has been compressed to zero — Bingo! Again we have division by zero, and again the error is hidden behind a “singularity”! (that is, “we” (science) have no clue as to what might really be happening, or how it happens). Science, at its best?
Another well known case where the error is accepted (where again a division by zero is said to result in “infinity”) is Einstein’s “velocity equation” (the “Lorentz factor”), as presented by Wikipedia (article List of Relativistic Equations):
γ = 1/(1–β22)1/21/2
where β = v/c and v is the relative velocity between two inertial frames. For two frames at rest, γ = 1, and increases with relative velocity between the two inertial frames. As the relative velocity approaches the speed of light, γ→ ∞.
Presented as if it was a cold, mathematical fact … Here, the error is shrouded by hands waving symbols around, but it all boils down to a division by zero, as follows: when v = c, then v/c = 1, and 122 = 1, and 1–1 = 0, and since the square root of 0 = 0, then 1/0 = undefined mathematical operation (i.e., an error) …
So far, the ratio of “bad science” over good ditto is singular: 3/0.
