Science Says: What Scientific Evidence Can Say About the
... These three characteristics are all well and good, but they fall on deaf ears if not for the evidence. As far as evidence is concerned, the Big Bang is the most "proven" origin theory known to science and mankind; namely, it has the most convincing evidence.
