haklyut,
As a stiff-upper-lipper you probably know, America was mainly founded by religious dissenters from the Church of England. They believed the Bible, not the king and certainly not the pope, was the sole spiritual authority as well as THE ONLY acceptable explanation as to how life began. Such beliefs became embedded in the American constitution, the documents forming the foundation of the government:
We hold these truths to be self-evident, that all men are created equal, that they are endowed by their creator with certain unalienable Rights, that among these are Life, Liberty, and the pursuit of Happiness">
Right there in our founding documents is the declaration that God created us.
This declaration is in conjunction with the first sentence in the bible "In the beginning, God created the heaven and the earth." The bible goes on to
say God created all life and also created humans, both male and female. It does not say how God did this, other than doing so from the dust of the earth.
Enter evolution. It says creatures change over time. Indeed they do, for example, bacteria undergo mutations and genetic recombinations
resulting in different species of bacteria, some with resistance to penicillin, some that can digest previously undigestible substances. This is a proven fact backed up by
enormous amounts of observed data. It is indisputable, just as it is indisputable that trees absorb water and nutrients from its root system, just as it is indisputable that
water freezes at 0 degrees Celsius.
In every instance, however, over hundreds of thousands of generations, the bacteria never change into amoebi or amphibians: they remain solely within the bacteria kind. In fact, there is zero evidence for any kind of creature (cat, dog, bird, deer, swine) ever becoming another kind such as reptiles becoming birds. There are supposed transitional forms like tiktaalik that is touted as "proof" that lizards became birds butthis is not any proof at all, just a possible interpretation of a few fossilized bones.
This is not an argument from incredulity, it is an argument from not accepting an impossibility, such as, it is impossible to accept that you donned scuba gear and a pair of feathered wings and flapped yourself up to the moon.
Building upon evolution is the Theory of Evolution. It says since living things can change over time (they can) then man was not created but evolved, over millions of
years, from a simple cell to more complex cells to a snail-like creature to a rodent-like creature to an ape-like ancestor and then to humans. This is in direct contradiction of
what the bible says and why the theory is opposed so vehemently: if the bible is untrue, Christianity is untrue.
Because the Theory of Evolution is not proven (except in the minds of some people), and that there is no evidence that humans evolved from an apelike ancestor only the
speculation and assumption that humans did so, it is therefore unacceptable to have this theory taught as a fact when in truth it is only speculation, a possible explanation
how humans came to be.
If some American institutions and groups of people would stop declaring the Theory of Evolution as fact and place it in its proper position, that is, it is an unobserved,
unproven explanation as to the origins of all the species, then there would be no argument. Mutation? Speciation? Adaptation? There is no problem with such teachings as
they are backed up by observation and testing. Issue is taken when adaptation and mutation are claimed to have resulted in all the life forms we see today, starting from a
single-celled organism changing through millions of years.
The argument really goes further than the debate on origins, because you have to go back to where matter came from and how life arose from that matter. Basically,
either matter has always existed and it moved itself to form living entities, or God has always existed and created matter and formed it into living entities.
Some people do not belief unliving matter can move itself and form stars and planets and life mindlessly and without intelligent direction so the default explanation is
God. Others cannot accept the existence of God and have to conclude matter just popped out of nothing, or it always existed and came together on its own from a soup of
random proteins floating around.
So there you go. In Britain most of the people have gone ahead and assumed the bible is false and the Theory of Evolution is true, and they have the numbers in
academia, politics, the media to enforce that this is the view which is taught to be true to the exclusion of other ideas.
In America, a political war is being fought to establish which view of origins is to be taught. Those who don't believe in God do not want their children being taught God
created us. Those who believe in God (mainly Christians) do not want their children being taught God did not create us.
Both sides argue that they are correct. Christians point to the bible and the existence of matter & living things as proof for God; non-Christians point to Darwin's theory as
proof.
I don't want to argue here which is correct. You have to choose for yourself which you will believe as an authority for the explanation as to how life arrived on this planet.
