Failure of one hypothesis does not constitute proof of another. It only means that the failed hypothesis must be discarded. You are referring to the famous and admitted Creationist hoax that was perpetrated along the Paluxy River in Glen Rose, Texas in the 1930's. For a detailed explanation, select the link below.

Random mutations produce changes in the offspring of living things.
Changes that make those offspring better able to survive in its environment allow it to flourish and produce more offspring. Eventually, the changed creatures may supplant its predecessor or become varied enough that interbreeding no longer occurs and a new species arises. If so please explain the Bombardier Beetle. A unique little beetle that has a defense mechanism of spurting out a highly combustible gas that smells horrible. This gas comes from the mixing of 2 chemicals which are kept in two seperate chamber then combined in a third then expelled through the snot.
