Hmmm...

Why is there such thing is good looking and bad looking?

Maybe a person appears to be good looking to you, but not necessarily I would agree with you.

So why do these conditions exists?

Every human is special in their own way.

Come to think of it, is that actually a good thing or a bad thing?

Why can't all males have the same facial features, and only a little difference here and there so that each men are easily distinguishable from each other, and the same theory for females?

Ah...perhaps we will never know until one day, all of mankind are just clones of one single man and one single woman
