You're joking, right?
No, not joking. Unlike some I have encountered here, I don't know everything. I guess that is kinda strange, and could be seen as a joke (laughing matter), though.
So you think if you don't know something, the alternative is being someone who thinks they know "everything"? That's stange.
In any event, if one person was a clone of another, that doesn't mean that their fingerprints will be identical, or that they will have the same number of hair follicles, be the same height and weight etc.
Just like animals who have been cloned don't look exactly the same.
These 5 colts are clones of each other...
As I said before, identical twins are natural clones of each other, and no one thinks that they are the same person.
Clones are exact copies.
If you had a clone, I'm pretty sure they would object if you told them you were keeping them around for spare parts.
