Evolution a fact of science? Part Two

When we deal with the issue of origins, we must realize that no people were there to observe and record the events. When scientists discuss the origins of the universe, the earth, or life on earth, we must realize that the discussion is based on assumptions. These fallible assumptions make the conclusions of the discussion less valid than if the discussion were based on actual observation.  Almost all biology books and textbooks written in the last two generations have been written as if these presuppositions were true.
Proponents of the evolutionary worldview expect everyone to accept evolution as fact. This is a difficult case to make when the how, why, when and where of evolutionary history are sharply contested or unknown by the scientists who insists evolution is a fact.
Evolutionists often claim that creation is not scientific because of unprovable assumptions that it is based on. The fact that evolution is based on its own set of unprovable, untestable, and unfalsifiable assumptions is recognized by many in the scientific community.
Within the scientific literature, the mathematical and chemical impossibilities of the origin of the universe and life on earth are recognized. Many notable scientists, including Sir Fred Hoyle and Sir Francis Crick, have gone so far as to suggest that life originated om other planets or was brought to earth by an intelligent being. These ideas are no less testable than special creation but avoid invoking God as our Creator.
