Real Life versus a Simulation of Life

"Be Right Back" presents a clone of a woman's husband that died. In the discussion of whether the clone was really him, we discussed how many of the clone's attributes were the same. However, there are many reasons why they could never be the same being and how a clone could never be considered a real person unless the terminology "person" is altered.
The husband and the clone husband looked similar, but the clone looked like the husband on a good day. In a scientific sense, Newton's third law states that matter cannot be created nor destroyed. This means that humans do not have the ability to create ,but only to compose things sense we are made on earth and our capabilities do not involve the creation of what is not already here. We cannot make elements, but  we can make compounds out of elements. If a clone is made then it's by products are secondary.

When people die, their body is no longer occupied by what drives them, but all of the parts that are used in driving them are still present: the vital organs, body parts, bodily fluids and brain, which are physical entities. The human composition is one that is so sophisticated and interrelated that figuring out human chemistry is impossible. People have supernatural healing in some cases. People are able to configure new things in which a robot or clone could not connect what is not already thought by a human to connect. Artificial intelligence is only recalling imputed information.
If a clone dies, what leaves them? Is their dying just a simple operation error that limits the connection of information to be configured or do they die like humans die?
If a human can create a human then who created human. However, humans cannot create anything nor humans. If a human can create something like a human this must mean that a something that is not human made humans like something not human sense we as humans can't make or create ourselves.Our mind goes as far as knowledge but where does the actual existence of the what we learn from and call knowledge from ?

Learning what a person is made of is a hard instance to accomplish. I believe that many people have not grown to learn their creator with what is given access to us individually which defines why they do not know themselves. We look at ourselves in the mirror, but do not look through ourselves in the mirror. Our vision is through us and if we look through our eyes to our eyes it creates a continuous loop that can reveal the limit on our minds and what we have access to as humans. I believe a robot or clone would be even more confused than we are if they look into a mirror and try to see themselves for what they are and even when animals do, it reveals their limited capacity.
Why does looking through our eyes into someone else's eyes make us so uncomfortable. Can an uncanny valley apply to humans seeing humans for what they really are. I may personally be disturbed by someone who could think to make and execute making some of the amazing technology we have today.
