Perhaps you'd (or anyone) care to explain one....

The Cambrian is the last stratum of the descending levels of earth that has any fossils in it. All strata below the Cambrian have absolutely no fossil record of life other than some single-celled types such as bacteria and algae. WHY?????
Bacteria suddenly turned into animals???????
The Cambrian layer is full of all the major kinds of animals found today except the vertebrates. In other words, there is nothing primitive about the structure of these most ancient fossils known to man. Essentially, they compare with the complexity of current living creatures. The real question is: Where are their ancestors????

If all life came about suddenly then....hmmmmmmmm....not evolution. Even Darwin knew this was a huge problem to the theory.... He said..."To the question why we do not find rich fossiliferous deposits belonging to these assumed earliest periods prior to the Cambrian system I can give no satisfactory answer...the case at present must remain inexplicable; and may be truly urged as a VALID ARGUMENT AGAINST the views here entertained" (evolution)
