A theory by definition is something that is not known to be a fact. Saying
one thing is both a fact and a theory is silly. The late Carl Sagan often
said that Evolution is a fact, not a theory. I suspect that many
Evolutionists think such honest expression of their beliefs sounds a little
too religious.

In regards to Evolution, what part is the "fact"? That all modern life
developed naturally from a common ancestor? Or, that alleles change in
frequency with time? Most any Evolutionist asserts that both of these are
facts. Now, what's the theory? That all modern life developed naturally
from a common ancestor? Or, that alleles change in frequency with time?
It's too bad you used plastic metals for your explanation of something being
both a fact and a theory at the same time instead of Evolution.

In regards to your plastic metals, you say "plasticity" is both a theory and
a fact. In your analogy, "plasticity" is a fact, not a theory. A theory of
why metal has plastic properties is not itself plasticity.

Thank you for the compliment.

Doesn't the fact/theory of ameba-to-man predict (this definition of
evolution is the one that is relevant) that there is an ability of nature to
increase complexity step by step?

It's interesting that you can address the fact vs. the theory of evolution
without identifying what you consider (and what the evolutionist community
considers) the fact to be and what you consider the theory to be.
