A lot of anecdotes and beliefs revolve around the thought that there exists a person who is exactly a copy of you.

A double-walker or doppelganger, whatever you wish to call it.

But the question is, do we really have a lookalike?

Folks tell that everyone has a doppelganger; somewhere in the chaos of 7 billion people on the planet, there is someone who looks exactly like you, a duplicate of you, who can have your parent's resemblance like you have.

Although science has a different narrative and it is also interesting.

According to the studies, "chances of sharing just eight dimensions with someone else is one in a trillion", even with so many people on the planet, there is only one in 135 chance of finding a single pair of doppelgangers.

Despite this, with her ability to perceive and recognise things by looking at them, we try to see familiarity in people, like someone's eyes, looking exactly the same as others, or it could be any other facial features.

This is how we go; according to this understanding, we all have somehow found someone looking alike.

But looking alike is not justified when just a few features match. It's a copy that cannot be even slightly different from you.

Furthermore, and interestingly, there's one more interesting narrative to the doppelganger story. Even though our features vary, our genes do not.

It is found that we are somewhere or else genetically similar.

So there are chances that certain features resembling yours do combine randomly, but that still would not make someone exactly the same as you.
