If light travels in straight lines, then there would be gaps left as the source of light emits light beams at an angle and therefore the space in between the angle would be left empty yet we do not see this empty space why is this.

Right, now that you're sucked in...

This is a little one for the creationists who frequent this board, my question is basically "why creationism?"

When ever someone asks a question about evolution I have noticed that there is always a creationist popping in with a "Evolution is all rubbish" comment and I want to understand how this works in their head...

I have had a think about it and I can see a few reasons why you might subscribe to the creationist argument:
1. You just believe in the Bible, Qu'ran, etc and this says that evolution didn't happen
2. You have weighed up the evidence in support of evolution and decided that it is irredeemably flawed
3. You have weighed up the evidence in favour of creationism and decided that it explains everything flawlessly
4. A mixture of the above

If the answer is anything but 1 you are partially basing your opinions on science (or perceived science) and I wanted to try and understand some of the main scientific ideas that creationists have.
