I see. So you believe that the belief in God as creator and designer of the universe is an intellectually challenging exercise because it is a flexible idea. So, for example, in the book of Genesis, it says the following

God said, “Let us make man in our image, in our likeness” (Genesis 1:26).

If I understand you correctly, this passage could be interpreted in many ways, but it is up to the individual to make this interpretation, and this makes it an intellectually challenging exercise. One could interpret this bible passage to mean that physically we look like God (thus God looks like a man). Perhaps, intellectually, we resemble God. Spiritually and emotionally as well. It is up to the individual to decide. Regardless of the interpretation, the idea is very advanced and intellectually challenging once you begin examining it closely, and this appears to be your main thesis. The devil is in the details, in a manner of speaking.

Sorry to pester you so much, but your thoughtful posts pack a lot of information, so it takes me some time to unpack it all :)
