Evolution is an incomplete explanation by science if it cannot explain origin.
Science would like to try to explain life, but must admit it cannot.
Evolution is incomplete, and any real scientist should concede that point.
Evolution does not explain how the first life form got started and does not propose to do so either. What evolution explains is speciation, how variants occur over time.
How the first life form(s) appeared is explained by bio-chemistry. The first life form(s) did not have eyes and ears and legs. The common objection that organs lying about in a field could not, by random shuffling, assemble themselves into a wolf is a straw man argument. The first life forms were extremely primitive, microscopic, not even as complex as bacteria, not more than a few bunches of molecules. Organic molecules have been detected even in outer space, in the tails of comets. These can indeed come about by spontaneous recombination or shuffling of the hundred or so naturally occurring elements, just like drawing a royal flush in a random shuffle of playing cards. No intelligent design is required to produce the basic chemical precursors of simple life forms.
Once the basic chemistry for life exists, and we are still not talking about mammals with organs or even anything as complex as a bacterium, but just the ability to reproduce itself and to store energy at a MOLECULAR level, THEN and only then does evolution show, by a combination of various mechanisms, including but not limited to mutation and national selection, how these extremely primitive life forms vary over time by adaptive modifications.
The common objection that life cannot come from not-life (from 'just chemicals' ) is also a straw man argument. Life does not come from not-life in one single improbable leap. There are identifiable in-between stages, there are states of matter which are not yet life, but not altogether not-life either. There are 'things' and chemical processes which exhibit some but not all of the properties we attribute to life. Photosynthesis, for example, is a chemical process we tend to associate with plants; there are however, plants which do not photosynthesize, moreover, photosynthesis can occur without being attached to any living thing. It's just a chemical process, but it is also one of the essential chemical precursors to life. Viruses, for example, are not alive, but not wholly non-living either-- not like rocks, for example. Viruses lack the ability to reproduce by themselves, but they exhibit other life-like properties. There are other in-between stages; for brevity, I haven't listed them all here. So, in sum, life did not come from not-life. There were many in-between stages along the way, and these in-between stages are still with us in many forms, we can see and measure them and even use them in manufacturing medicines and vaccines (for example).
Now, take it to Science, Spanky and stop confusing separate branches of science you know little or nothing about. You wouldn't expect a zoologist to explain an electronic device would you?
