What are some specific arguments with support against cloning? I know of ethics, but I need elaboration on this.
I know of reduced genetic variation as a negative, but elaboration on this as well. What is another specific argument why cloning should be banned. Initially I thought of the imperfections of cloning but it was vague so I need another topic. Thanks.

Evolutionists are telling us that we came from ape and after billion of years in the process we became man.
They also told us that in the begining, life forms in earth originated from bacteria that leaves in the water and transformed into another life form and so on until the multitude of living species evolved.
Evolutionists also tell us that EVOLUTION is CONSTANT CHANGE.., now, my question is WHAT EXACTLY WILL BE OUR CONFIGURATION AFTER ONE BILLION YEARS AHEAD IF THERE IS CONSTANT CHANGE? is evolution a fact or a lie?

Looking at all the facts, the species Homo Sapien (human) seems to have the longest record by far for tending/raising their own offspring.

Most animals in the wild only 'put up' with their children until they are sexually mature.

Humans can sexually mature anywhere from 9-15 years of age.

How is it then, it that case, that:

1) We keep raising our children so much longer than biologically necessary?

2) Most women become fertile again either immediately or soon after giving birth, which suggests that our biological law requires us to produce one offspring at least once a year. How on Earth would a single human (or even a partnership of humans) raise and tender to all of their children if they had at least one every single year?
