Is it normal children dont know how to describe things?

This has happened on more than one occasion but not with every single child. I have asked a child to describe something which they lost or person they lost to help them find it. It goes like this.

Okay well what do they look like

They had a face
They have hair
They are wearing clothes
The have a gender

If its a thing

Well what did it look like

Its a thing
It was a color
I lost it
Its no longer with me

Why do they describe things like this? I mean you cant get mad since they are children but its just terribly unhelpful.

I mean I can say I didn't do this and I was terribly descriptive but I was by no means a NORMAL child. I was also very picky and OCD so if things were not EXACTLY one way it upset me.

Like I had the neighbor kid asking random people saying they lost their brother. So your like "Well what do they look like"? If you ask them to specify. "What color shirt are they wearing" and they say "You know a shirt".

Why do kids do this? I mean its really funny but I dont know how to work with that.
