But to have accomplished that, they would've had to change his lower eye to the other side of his face, enlarge his eyes and change their slant. His hair was already naturally parted on the left, so why would they change it to part on the right? People need to look at the finer details in all of this; it's what makes only the artificial replication theory plausible.
