I wasn't trying to define "science". Are you claiming that there
is a scientific fact known with 100% accuracy and certainty? How about a
scientific theory that attempts to describe how the universe operates?

I was addressing the issue of what it means to observe evolution. You can't
actually do it in the way that some here have suggested would be required
in order to verify that evolution is an accurate theory (you can't do it
because it is logically impossible given the definition of what evolution
is).

If you travelled in a time machine from 1 billion years ago in the past,
through to the present time, pausing to sample life every 100 years, you
would observe NO EVOLUTION! However, you would notice that life has
imperceptibly got a LOT more complex than it used to be, and a lot of
things are walking around now that weren't walking around before.

You can only observe that the "final" product is significantly
different from the initial product.

For an example of how you CAN observe evolution, I am told that if you
study a large variety of different species (particularly in the oceans),
you can observe a vast array of different light-sensing organs. Taken
together, you can observe how an eye can evolve.
