Yes, they would, but they won’t because the stakes are much too high for them since if the Big Bang is false then it logically follows that evolution is as well. They’ll be revealed as charlatans, deceivers, stupid pagans and worse. Rather, like rats in a trap seeking a way out, they’ll revise the second law of thermodynamics if they can get away with it.
In the meantime, there is no evolutionary biologist in the world who believes that the change in allele frequency in a population has the slightest bit of anything to do with the Big Bang.
