Gday all,
Some more thoughts on all this -
Theories are accepted based on EVIDENCE
So,
why did the Phlogiston Theory of Burning get rejected in favour of the Oxygen Theory of Burning?
Why did the Germ Theory of Disease win out over the Demon Theory of Disease ?
Obvious isn't it?
Because we FOUND germs.
And we found Oxygen.
We OBSERVED them, and saw their effects.
(And we never ever found Demons or Phlogiston.)
Theories do NOT get promoted to laws or facts
A theory does NOT get 'promoted' to a law or a fact when it is confirmed (or 'proven' in layman's terms, which are best avoided.)
The Oxygen Theory of Burning did NOT become the 'Law' of Burning once oxygen was confirmed.
The Germ Theory of Disease did NOT become the Germ Law of Disease when germs were observed.
These days - scientists tend NOT to make 'laws' anymore - it's considered out of date, mechanistic, Victorian.
The 'Law of Gravity' is an example of an old classic - and it refers to a clear and specific simple mathematical relationship F ~ m / d^2
There is ALSO a 'Theory of Gravity' - well, there are TWO :
- Newton's Theory of Gravity
- Einstein's Theory of Relativity (which covers gravity)
One is about 99% accurate and stood for 4 centuries, the other is 100.000% accurate and is about one century old.
Evolution is 100% supported by evidence
So,
Darwin (and the poor forgotten Wallace) had a theory (explanation) to explain the origin of species.
(NOT the origin of life.)
Darwin's Theory of Natural Selection explains how species arise by a process of mutation and natural selection over relatively long periods of time.
Darwin proposed his theory based on his observations of living things, but of course initially it was speculation.
So why is it accepted?
Why is it considered true?
Why do we insist it's NOT speculation now?
Why is Darwin famous like Einstein?
Because we have OBSERVED that he is RIGHT, just like Einstein, every single time.
It's been 150 years now - in that time there have been MILLIONS of tests and observations and experiments by THOUSANDS of scientists in dozens of countries which could have either :
- supported evolution
- disagreed with evolution
The score so far is:
- MILLIONS - for evolution
- ZERO - against evolution.
THAT'S why Darwin is famous like Einstein.
And THAT's what creationists don't seem to grasp - just how clear the result is - and just how VAST the amount of evidence that supports evolution is.
Evolution is an observed fact of nature.
It's not just some 'speculation', not just some ol' 'theory'.
