Much of the debate concerns evolution v creation. Both defy logic. Evolution basically involves a fish that crawls up onto the land, and is fortunate enough the meet another crawling fish. They mate and have a baby monkey who grows up to meet another monkey. They in turn breed and yet another step is taken along the evolutionary path towards are present existence.
Creationists believe all things were made by God. Differing religions have different theories on how their own version of the supreme being went about his business. Then there are always those that like to combine the two and throw aliens into the mix just to complicate matters.
Personally, I tend to side with religion. Not because it is any more logical, but because I'm lazy. The seeds were planted back during my school days. Science lessons involved potions, compounds, periodic tables, complicated Latin names and difficult equations. Where as Religious Studies, Divinity or Ethics as it is frequently referred to today, was usually taught by a wet liberal that told stories and rarely sought retribution for neglected homework.
Probably the best option would have been to side with Physical Education. A good healthy sports obsession can eliminate the need to even consider such complex ethical questions.
