If evolution is a fact then prove it. Facts are proveable and observable right? Why don't you educate me?
Evolution for Beginners
At a minimum, three things are needed for evolution to happen. Birth (we know that happens), death (we also know that happens), and genetic variation (and we know that happens). More specifically, 1) the births of many more individuals than can survive, to give the maximum genetic potential; 2) the disproportionately high percentage of deaths of organisms who are less well suited to their environments and predatory conditions, and therefore are unable to leave as many offspring; and 3) genetic variation to produce the raw material of physical change, which is then acted upon by natural selective forces. All of this has nothing to do with the species wanting to evolve into another species. Creatures do not choose to evolve. If the environment and food supply changes, or if the species relocates to a new environment, or a new species enters the area and competes, evolution will probably occur- or the species may become extinct.
Evolution is a Fact and a Theory
From a respected Biology textbook:
Since Darwin's time, massive additional evidence has accumulated supporting the fact of evolution--that all living organisms present on earth today have arisen from earlier forms in the course of earth's long history. Indeed, all of modern biology is an affirmation of this relatedness of the many species of living things and of their gradual divergence from one another over the course of time. Since the publication of The Origin of Species, the important question, scientifically speaking, about evolution has not been whether it has taken place. That is no longer an issue among the vast majority of modern biologists. Today, the central and still fascinating questions for biologists concern the mechanisms by which evolution occurs.

Same warning as for

"History I believe furnishes no example of a priest-ridden people maintaining a free civil government. This marks the lowest grade of ignorance, of which their political as well as religious leaders will always avail themselves for their own purpose."--Thomas Jefferson
There is no greater threat to civil liberties than an efficient government. -jar
