Yeah, the whole string braneworld and landscape granola is fun and interestimg, but completely hypothetical. You can use it in an argument to illustrate e.g. how anthropic selection could work without a god, but you cant make hard conclusions from the fact that it exists, cause you don't know.
The fool hath said in his heart, There is a God. They are corrupt, they have done abominable works, there is none that doeth good.
Psalm 14, KJV revised edition
