I see you have run out of arguments. That's too bad, but not surprising, as you are trying to prove what can not be proven. Dawkinsrocks is also trying to prove the unprovable, but has not yet given up. I guess that means he has won the "prove what can't be proven" debate.
To sum up, here are the possibilities:
The Earth, with its complex and highly orderly web of life, just happened with no cause, no intelligent guidance at all (highly implausible, of course), or
There is an intelligence that has created it all, whom we refer to as god, but none of us has ever seen that god or any evidence that he/she/it/they exist, other than that creation (also highly implausible).
One of he implausible ideas has to be true, but proving which one it is is not possible.
Personally, I subscribe to the hypothesis that the creation proves that there is a creator, but, then, I can't prove that either.
