Evolution mean “change in time.” In biology, this means “change in biological entities in time.” Some may ask how did species come to populate the Earth? Where did the diversity of life that we have upon the Earth happen in time?
If the definition of evolution is changing in time, then the opposite of evolution is, clearly, not changing in time, or “stasis,” which means to stay the some in time. Things either change in time, or they don’t change in time. Those are the two opposites that must be considered when discussing evolution. Has the distribution of life on Earth change in time, or not change in time? If it’s change in time, then evolution is a fact; if it has not changed in time, then evolution is an error. So all we have to do is identify what has occurred in the past, in order to determine whether or not life has change over time. There is another question one could ask, “How in time did life come to be on the Earth?” One answer could be what science provides, according to certain rules that science choose to follow. Another answer could be God put life here. However, this is a statement that cannot be proven or disproved according to the rules of science, and it therefore is not a scientifically valid statement. Science is agnostic on God; it takes no position on God. If we chose science and God (which many people do), then one rephrases the question slightly: How, according to the rules of nature, did God create life on Earth? This is really the same as “how, according to the rules of nature, did life appear on Earth?” which is the question every evolutionary scientist is trying to answer. Whether one believe in God or not, the results, when conducted scientifically, should come out the same. The idea of evolution is one of the truly great ideas humankind has ever expressed.
