Between your atrocious spelling and your incoherency, it is difficult to extract meaning from your post...
Natures laws are not set. Human laws that explain observations and allow us to make successful predictions are "set" until an observation is made that forces the law to be reevaluated or rejected, or a better law is developed, one that makes more accurate predictions.
As far as the Big Bang theory is concerned, it is based on observations of the physical universe, and makes valid predictions. Creation mythologies are fiction, and don't predict shit.
Examples of natural selection on a macroscopic level:
Mass extinction at the end of the cretaceous period due to asteriod impact 65 mya.
Spanish Flu pandemic, 1918
AIDS pandemic 1940(?)-present
SARS
Another of my rants, given to a former student during his freshman biology class:
1. What is your personal opinion of the evolution vs. creation debate in
public schools?
There is no debate. Proponents of "Christian creation mythology"
(see 3B below) have put forth that this is a debatable issue, but it is not.
Science is a system for explaining and predicting observed natural
phenomena. Religion is a belief system based on a mythology. Each serves
its own purpose. Would you use a religious text to determine the melting
point of an aluminum alloy, or the chemical formula for trinitrotoluene, or
the crystal structure of molybdenum? Would you use a physics book to
determine which deity to worship on the first full moon after the autumnal
equinox, and what sacrifice is appropriate, and which prayers to chant?
2. Should evolution be taught in public schools? Why?
If science is to be taught in public school, then evolution needs to
be taught. The modern theory of evolution is THE most important
foundational theory that the science of biology has ever put forth.
Teaching biology without teaching the modern theory of evolution is not
teaching biology. Replacing the modern theory of evolution with Christian
creation mythology is an insult, and would result in a nation of ignoramuses
mocked and ridiculed by the entirety of the enlightened world.
3. Should creationism be taught in public schools? Why?
Not as a substitute for the modern theory of evolution.
A) Public schools are funded by tax dollars. The U.S. constitution
explicitly separates church and state, and teaching Christian creation
mythology would violate this tenet.
B) Who's "creationism" would we teach? Christianity? Native American?
Satanism? Islamic? Buddhist? Norse? Roman? Pagan? Wiccan? Last time I
checked, this is not a monotheistic country, yet "creationism" has come to
mean, within the context of this discussion, "Christian Creation Mythology".
"Creationists" or "Creation Scientists" (a term that is laughable in its
inherent contradictions) support only their own explanations for our
existence, and furiously reject any other, be it "evolution" or "we live on
the back of a giant turtle". They only see the world one way, the way that
they have been trained to see it, and reject any evidence that invalidates
their beliefs.
C) Christian creation mythology is a mythology. Mythology, though
often a source of entertainment and lessons for living life morally, is not
a science. I teach science.
D) I find the concept of replacing the modern theory of evolution with
Christian creation mythology to be offensive in the extreme. It rejects
thousands of years of scientific exploration, an organized endeavor of
knowledge acquisition, assimilation, synthesis, and expansion, that is
without parallel in any other human sphere, in order to preserve the
perceived "validity" of a mythology embraced by a religious minority. This
is supreme ignorance.
4. As a science teacher, do you teach either and why?
I teach the modern theory of evolution. I discuss Christian
creation mythology only briefly, and in the context of a discussion creation
myths found in a number of different global cultures and religions.
