Teaching of evolution does not present a problem to you because you believe in it. However, a person, such as my son, who believes that God formed man, would have a serious problem with anyone that teaches that God used another method. It is a method that runs counter to what he believes is taught in Scripture. Because it is, as you admit, a theory, should a teacher be allowed to undermine his religious convictions?
What do you mean "another method"? Where in Genesis does it say what method God used?
In Genesis 1 it says that man was created in God's image. Doesn't say how. In Genesis 2, it says God created man from dust. How'd God do that?
Did God pick up dust and change it's atomic structure? Did he perhaps sort through the dust to find the molecuels He wanted and assemble them chemically? Did He use some kind of chemical vats, or physical jigs to hold the bones in place while he placed the muscles and skin?
The big question is, how long did it take? Genesis 2 doesn't say.
I say God is very patient, and it took him about 2+ billion years. And His toolbox is a nifty thing called Evolution.
The simple fact is, Genesis doesn't say. And for you to impose your simple understanding of the universe and claim that He COULD NOT have used Evolution, I believe is arrogant.
