It's a common misconception that most christians believe in creationism. The vast majority of Christians are Catholic (like me) and catholics accept evolution. So believing in creationism puts you in the minority even among cristians.
I personally like to believe that science helps explain god's methods rather than refuting him. The idea that God would have to intervene with the natural workings of his own creations would imply that he made them flawed from the start, which doesn't fit well with him being all powerful.
That's why if you really want to learn about the divine creator, you should study the universe not the bible, because god actually created the universe.
Creationism, expressly "Young Earth Creationism" , is almost the soul reserve of a small group of ultra right wing evangelicals in america and very small numbers elsewhere. Islam is actually MUCH less open to the idea but that is another thread (Over 70% of people in Turkey don't beleive in evolution for instance).
Actually there is a VERY small sect of Christianity that the weird mutation of "Young Earth Creationism" comes from. Creationism as a word has been bastardised; the term in the 19th century jusr referred to ANY beleif in a devine creator. Creationist theory is mainly a 20th century manipulation of the missconceptions of well-meaning 19th century scientists attempting to reconcile their faith with science who righfully raised doubts back in a time when Evolutionary theory was in its infacny.
Here in the UK even the majority of the Evangelical Church is in no doubt of evolution. Infact you would be hard pressed to find any people who are enthusiastic supporters of the idea that evolutionary theory is wrong.
