I am not one to believe that religion and science are at odds.
The big bang, evolution, etc. are theories. So is creationism. They are both theories because neither were witnessed first hand by any of us.
I personally believe that God created everything. Whichever way it was created, it was not an accident.
So in short, I believe that either both, or neither, should be taught. We must have a free will and choice to determine what to believe.
But evolution being taught to children in school as fact is wrong. Sadly, this is typical of our disinformation system.
