Evolution Is Just A Theory

"In casual speech scientists don't use the term theory in a particularly precise fashion." For instance: "Einstein's relativity is usually called 'the theory of relativity' while Newton's theory of gravity often is called 'the law of gravity.'"

But the "theory" best explains why the universe acts as it does. Newton's "law" imagined gravity to be, simply, a force that pulled on everything.

Still, despite the fact that Newton's force doesn't exist, it's easier to accept and comprehend than a four-dimensional universe in which orbits are straight lines.

Onward: I think it's best to think of a theory in this manner: "a testable model that is best capable of predicting future occurrences or observations and capable of being tested through experiment or otherwise verified through empirical observation." (Love you Wikipedia, and I promise not to forget Valentine's this year)

Einstein's 4-D universe allowed humans to, for the first time, explain why Mercury's orbit is what it is. And so on.

His models, theories, and theory of models currently best explain the universe. The universe could, in fact, be exactly as he explained it. Nothing has proven him wrong.

Still, the 4-D universe will always be just a theory simply because humans don't have access to every happening everywhere at any-/every time.

Then there's Cell Theory, which "refers to the idea that cells are the basic unit of structure in every living thing." ... "The theory says that new cells are formed from other existing cells and the cell is a fundamental unit of structure, function and organization in all living organisms." (Wiki)

Obvious, it seems. But still just a theory.

Now to (biological) evolution.

It's 100 percent true, factual, proven, unable-to-be-disproved that organisms change over time. You can watch organisms with short life spans evolve (develop; change over time). Organisms like bacteria and viruses that cause illnesses in humans; like the flu virus, which portions of the population are immunized against each and every year because each and every year the virus has changed enough to make the bugger immune to your previous year's immunization.

So, if you don't believe in evolution, you have the unfortunate habit of proving that evolution happens/has happened every single time you get sick. And you get sick an average of three times a year.

Evolution happens. You state its reality with sneezes and to your boss whenever you call in to work when you actually need to.

Here's the sticky thing:

The theory of how evolution works continues to be refined.

Meaning that evolution is just a fact that has a continually more precise theory behind its whats and wherefores.

PS: Creationism/Intelligent Design disproved: the duck-billed platypus.

The. End.
