The Bombardier Beetle
If there is any creature on Earth that could not possibly have evolved, that creature is the bombardier beetle. It needed God to create it with all its systems fully functional. Evolutionary theory has big problems when attempting to explain the existence and complexity of the bombardier beetle.
Each stage in the evolution of its special chemicals would have wed to its destruction. This one-half inch insect mixes chemicals which violently react to produce something similar to an explosion. How could the bombardier beetle have evolved this means of defense without killing itself in the process? This problem has the members of the evolutionary establishment scratching their heads. Evolutionary theory says that you do not evolve something until you know you need it. In other words a new enzyme or chemical or organ or fin or beak or bone will not evolve until the creature realizes it needs the new improvement.
The bombardier beetle would not have known it needed a mechanism to prevent these chemicals from blowing it up until it mixed the chemicals and blew itself up. Naturally, it could not evolve after it was dead, so how did it get here? The evolutionists say, "We don't know."
