As indistinguishable as a herd

Imagine a herd of sheep or zebras . All alike , similar & indistinguishable. All with same colored wool or all with black & white stripes and almost the same sized .
What if I loose my sheep in this herd . How hard it might be for me to find it ?
I may manage to find it only if there is a distinguishing character or any uniqueness. Right?
Similarly if 6 billion humans were all alike fair,tall,smart or what ever quality we imagine in a perfect person. Won’t it look just like the herd ?
NO identity NO uniqueness.
Imagine how bizarre the world would look.
