creationism | Definitions, History, & Facts
[kind of dubious that the article goes on to say, "It is a response primarily to modern evolutionary theory," since the idea of creationism was definitely there before the evolution theory.]
So we're not talking about biblical view to creationism alone.
I, as a Muslim, believe in science (in the sense that I acknowledge what has been achieved and found by it and that it is useful to study) and I don't deny much of the evolutionary theory, nor do I confirm it. I don't think it's important. The main thing about it that Muslims object to is the creation of man and that he supposedly evolved from the ancestors of monkeys. So there's plenty of room for science.
But there doesn't seem to be room for creationism anywhere according to some atheists and even some hypocritical believers.
What is the harm in it being said that God created everything? The children are going to hear it anyway.
In my opinion it is nothing but one of the many tactics used to attempt to annihilate religion, belief, and righteousness.
