Is human cloning real?
Certainly. Check out any pair of identical twins.
Now, if you meant artificially, it is hypothetically possible, although it's unknown whether the clone would be healthy and live normally. After Dolly the sheep made headlines most countries preemptively outlawed trying it with humans.
Thus far nobody has gone public with a successful attempt and would likely face recrimination from the scientific community if they did - the ethical concerns here are very serious.
