Not completely, CMBR. I agree that convincing proof will not be available in my life-time, perhaps decades or a few centuries later, but I would not replace it with "Goddidit".Science will never have convincing proof in my lifetime, to show how the universe and life came to be. We have lots of interesting and conflicting ideas, but no hard evidence how matter and energy first came into existence. To be fair, the BB, probably destroyed any pre-existing evidence.
"CMB is landmark evidence of the Big Bang theory for the origin of the universe."
