Human cloning should be banned(debate topic)(correct my english plz)

Imagine someone exactly the same like you with same capabilities and someone who looks identical like you.

Secondly, if we ban human cloning then science will not improve, humans will not see any scientific progress or developments in human genetics. However from religious people’s perspective we only have a one body given by god that we have to cherish and we should not try to replicate a new one. Also, if scientist create a human clone this human copy might be a threat to society who knows maybe they will be dangerous to human kind. In my opinion, we should still try to progress in science.

Nice job.  It's a little short.  If I were you, I would talk about how Korea (country) shouldn't ban it because inevitably there will be a country that doesn't ban human cloning or genetic modification.  If those countries have more lax laws in this field then they will advance and have a competitive advantage over countries that don't have the ban.  They could clone people with highly intelligent traits that could possibly enable them to take over the world.
