Hi binadub
it seems that the strong anthropic principle was implicated in his change of mind towards deism. This principle is based on the huge number of cosmological coincidences that are needed for life to exist on earth.
M-theory (the multi universe theory), some scientists believe, provides an argument against the strong anthropic principle. But M-theory is still contentious (though exciting) and scientists have different opinions about it. Same goes for the anthropic principle - it too is contentious. Cosmology is still in its infancy
