"big bang theory was literally invented... who was angry at God?"
If this were true, wouldn't it mean that the theory would only survive peer review if the reviewers all were angry at the same god?
And if so, if anyone who isn't god-angry enters the study of cosmology and comes to review the Big Bang, and the evidence that led to the formulation of the theory, they'd be able to refute it.
Not just reject it, like the OP, with derogatory motivations assigned, but actually point out the errors in either the observations made, or the conclusions reached. But an actual refutation....
