Which "it" are you referring to? Creationists seem to reject all the "its".<quoted text>
How does science explain it? There are theories than I can remember,which one is right? Tell me.
Here's the thing about science that gets your goat. It is incomplete and prone to error. But guess what? It's the best thing we've got.
In fact, it is the *inevitable* direction that reason takes. The opposite of science is faith, based on a feeling.
You are just wrong to reject science because it is not complete. And you are wrong to accept the Bible as being a source of revelation.
Arguments such as the Cosmological Argument or the Ontological Argument or the Argument From Stuff-Looks-Pretty-Therefore-G od-Did-It are philosophically juvenile and generally rejected by thinkers in the field. In fact, the only people I can think of who accept these arguments and use them are Evangelical rhetoricians like William Craig or the Banana Man.
Perhaps we disagree on that, but them's the breaks.
