Well, for one, you are assuming that there had to be an intelligent to kick the BB into place. Second of all, when it comes to physics, you are also assuming that there had to be an intelligence to 'design' the rules. Why? THe thing is, assuming an intelligence does not explain how that intelligence got there. To then say this supernatural intelligence is 'eternal' is a special pleading. Why can't the conditions that allowed the BB to occur also be 'eternal' , but without the added complexity of needing intelligence?
The words " I do not know" does not imply any deity.
