Before you ask another question like this, maybe you should study evolution - just the basics would do.

Ok, explain dogs then.
The fact that a horse and a donkey are two different species, yet they can mate and produce a mule (which is sterile) doesn't prove anything about evolution. It just says that they are different species. This also happens with Horses and Zebra's, and lions and tigers.
Evolution is more about the survival of the fittest.
Even if you believe in God, evolution still exists, it's not a like it discredits your belief of how things started completely, you really think that we would look like Adam and Eve?

No, that is quite wrong. Firstly, you don't get to redefine terms like species and evolution to suit yourself. If you want to argue with science, you accept the scientific terms or you are making a strawman or false argument.
Biological evolution is any change in the frequency of alleles in a population of organisms. An allele is a variety of a gene, which contains a mutation compared to another gene from a different organism of the same species. Such mutations are easily detected by genome sequencing, which is a form of chemical analysis.
This definition has been in use since 1939 -1940, so you cannot claim that the meaning is always being changed. It does not have to produce a new species immediately or even after a very long time. But over multiple generations it usually produces organisms where the genetic differences have accumulated to the point where new species form.
A species may be defined as a population of organisms which is unwilling or unable to breed with another population no matter how similar they may be superficially and produce fertile offspring. This is usually because the two populations have diverged sufficiently through genetic drift.
