I've never understood this argument. If an INTELLIGENT being produced the conscious entity, who or what was responsible for creating this intelligent being?

And no, you can't side step this question. You can't say "well, it's god" because that's special pleading. I just don't understand how people can assume that evidence of complexity requires a designer, but never seem to have a problem inventing said designer out of thin-air as a magically preexisting entity.

What's more likely: that a natural process of change followed by selection essentially navigated through an infinite search space of possible configurations, some of which would create things like intelligent life, or that there was, magically, a pre-existent eternal intelligent being that decided to create other intelligent beings?
