Whenever you see evolution arguments based on DNA, throw them out. Nothing could have evolved from raw chemical soup into DNA, and for sure not
humans. If all the matter in the entire Universe was amino acids, there is not enough matter to have the probability statistically to make DNA, and
DNA is a small part of a cell made up of thousands of elements that inter-react to cause life to exist.
The human genome is made up of over 3 billion base pairs of DNA, NOT counting so-called JUNK DNA which we are just beginning to investigate. We
assume so much in medicine and science, and we always look for simple solutions.
Logically, if we could even make DNA from chemical soup, and we had one and only one miraculously formed base pair, it is not enough to make a life
form that replicates itself. For evolutionists, they must accept that the impossible happened....a long sequence of DNA suitable for replication with
itself was encased in a cell wall with mitochondria and so forth to nourish it and keep it alive. Then, as if that could possibly happen, that
"simple" DNA sequence would have to add 1 successful base pair every year for 3 billion years to make the human genome we have today.
It takes more faith to believe in the above than it does to believe that someone or something intelligent arranged the molecules needed for us to
In my world, I call that God.
I don't see where a creationist is stretching the truth as much as an evolutionist.
To specifically answer the OP, I suspect that like designs make it possible for us to use them for food. I'd have a hard time eating a silicon-based
lifeform, for example.
Second specific answer to the OP: because it is economical to use like creative systems...liken it to an assembly line.
Third reason, so we can appreciate how these lifeforms may be feeling, reacting, etc.
