   Let's say you live on a golf course.  Like many of your neighbors, you love to wake up early and play a couple holes before you go to work.   One morning, you roll out of bed, get dressed, and walk out your back door onto the 7th hole fairway.  You notice that the grass is wet.  Not just dewy wet, but really wet.  Why, you think, is the ground wet?

     Logic might lead you to the obvious conclusion that it rained the previous night.  But does a wet ground prove a recent rain?  Not necessarily.  Maybe the underground sprinkler system watered the fairway.   Although one would expect the ground to be wet after a rain, a wet ground doesn't necessarily prove it rained, because precipitation isn't the only way the ground can get wet.

    What does this have to do with evolution?  Everything!   Evolutionists love to point out that some animals are similar to other animals, and then insist that the similarities prove evolution.  But what we have is the golf course problem all over again.  Although animals should be similar if evolution is true, do similar animals prove evolution, or is there another possible explanation that isn't getting a fair shake? If God created the world, wouldn't we also expect to find similarities in different animals?

    Many vertebrates have basically the same skeletal structure.   Many animals have two forearm bones, and two bones in the lower leg.  Mammals give milk.  Reptiles and birds lay eggs.  There is a definite pattern to the world we see.  Does this pattern necessarily prove evolution, or could it signify the existence of a common designer?  Because we would expect to see this pattern in either case, similarities alone cannot PROVE evolution.

    Many evolutionists also like to use the concept of "genetic distance", which measures the difference in DNA and protein structure, etc., of different animals to determine how "close" one animal is to another.  For instance, some evolutionists claim that humans are 95-99% similar to chimpanzees.   Because of this observation, they insist, one can conclude that humans must have evolved from apes.

    But the genetic distance between two animals depends on the chemical being tested.  One type of chemical test may show the two animals to be very close relatives, while another test may show them to be more genetically distant.  For instance, one type of blood precipitation test gives the impression  that the chimpanzee is man's closest relative.  However, if we consider this test as evidence for evolution, we must consider the following as evidence against evolution:

"Milk chemistry indicates that the donkey is man's closest relative." (2)
"Cholesterol level tests indicate that the garter snake is man's closest relative." (2)
"Tear enzyme chemistry indicates that the chicken is man's closest relative." (2)
"On the basis of another type of blood chemistry test, the butter bean is man's closest relative." (2)

    If genetic distance tests are proofs of evolution, shouldn't we conclude that we evolved from the donkey, or the garter snake, or the chicken?   Because they do not give consistent, definite answers,  genetic distance tests cannot be relied upon as evidence for evolution.
