Alan,
It does not frighten me.
Well, let's see shall we?
I just find it impossible to bring myself to believe that I was brought into existence by unguided natural forces.
That's the argument from personal incredulity - one of your favourite logical fallacies.
It is a logical impossibility with a probability of absolute zero.
And that's just an argument from assertion - why on earth would you think it to be "logically impossible", rather than that you find the notion that no god is necessary for your existence to be too difficult to face?
The forces driving the evolutionary process may appear to be unguided...
Yes, because they are.
...but there is evidence in our own brains that conscious will can interact with natural elements to bring about human creativity.
Non sequitur and it says nothing to the evidence that "conscious will" is in fact just an emergent property of our material selves.
The Bible tells us that we are made in God's image, which indicates the source of our creative ability.
No, it just tells us that
the Bible indicates that. The Bible is a book.
If you don't happen just to assume
a priori that this book is accurate, then you don't have to trouble with tying yourself into logical knots as you do to deny the reason and evidence that contradicts you.
Are you frightened of the real answers? More like terrified I'd say, and you have my sympathy for that - finally realising that your "God" is a fiction would I think be very painful.
