Intelligent Design is God of the Gaps writ large.
Materialist Evolution doesn't explain why there is a universe (or multiverse) in the first place.
Theistic Evolution has to deal with the problem of evil writ large, i.e. why would a loving Creator create and destroy whole species in painful ways over millions of years just so mankind could be the position it was in when Christ arrived.
There is no simple solution. Banging on one theory without admitting the problems with the other theories is misleading at best, and dishonest at worst.
Because it's not intended to.
Your argument here is like criticizing a saw because it's not a hammer.
Do not confuse a theory of evolution with a theory of "everything".
