"You" are not the atoms in your body but the pattern of atoms. Your consciousness is an emergent feature of that pattern. So, if a person was cloned, arrangement of atoms exact to its predecessor, is it the same person?

I guess this question boils down to what makes a body a 'person' as most would consider consciousness (inc. memories, thoughts etc.) to define individuals, rather than the exact atoms of the body (as 98% of these are replaced yearly anyway). However, this defies our perception of what makes a solitary entity- you wouldn't regard two trees to be the same tree just because the arrangement of atoms are identical to each other.

Saul Kripke argued that an essential feature of "you" is your history, i.e. who your mother and father were, which sperm entered which egg to produce you, etc.  A replication of you would not meet these conditions and would not therefore be you.
