Would you bet your life on it? Big Bang proof supposedly came from: 1. Redshift 2. Cosmic Background Radiation 3. Deuterium and baryogenesis what else? Is there no other way for them to occur without the Big Bang? but there is this Colliding Branes Theory about two branes colliding and producing the Bang everywhere. Meaning it doesn't occur at a single point but at multiple points so not really Big Bang but Multiple Bangs. Is it a leading candidate against the Big Bang theory or does the colliding branes theory produced a singular Big Bang too? Do you have list of all the evidences of the Big Bang in a site so any theory against it has to explain each point by point?
