No, most people have observed it including yourself. Evolution is defined simply as occurring change or change is ongoing or a observed fact. The Theory of Evolution explains the observed fact. For the simplest proof there are 6.7 billion people on earth and no two have been found to be exactly the same so some change has occurred. Get a picture of your parents and stand in front of a mirror. If you are exactly the same no change has occurred and you are a clone. However is if there is any difference, no matter how small, some change or evolution has occurred. Evolution whether by reproduction or nature is still change.
Evolution is both a fact and a theory. What is a theory? The method of science is the observation or a material fact (evolution) evidence and empirical evidence of the fact (evolution), and a explanation of the fact that constitutes theory. A scientific theory is composed of facts and laws not someones opinion.
If by now you have looked in the mirror you may remain a clone in thought but that physical change has occurred is a material fact observed by your own senses.
The many slight differences which appear in the offspring from the same parents, or which it may be presumed have thus arisen, from being observed in the individuals of the same species inhabiting the same confined locality, may be called individual differences. No one supposes that all the individuals of the same species are cast in the same actual mould. These individual differences are of the highest importance for us, for they are often inherited, as must be familiar to every one; and they thus afford materials for natural selection to act on and accumulate, in the same manner as man accumulates in any given direction individual differences in his domesticated productions.
