Here is a good rebuttal to the idea that scientists have “faith” in evolution and don’t want to rock the boat, lest they risk their careers:
Science has always reserved its greatest accolades for those who prove what came before to be wrong, and every scientist in the world knows the best way to become famous is to prove everyone else wrong. Nevertheless, pseudo-scientists always argue that scientists have some vested interest in preserving the current order (and thus dooming their careers into obscurity when they could have become famous Nobel prize winners).
This argument has never made any sense, but that doesn’t stop them from making it. So, one more example won’t make any difference to them — people who advocate a bad argument that runs counter to evidence are not dissuaded by more evidence.
The point is, if a scientist found evidence against evolution, he would have every incentive to publish it and argue against evolution. If they could make their case, then they would earn their place in the history books, along with Kepler, Copernicus, Darwin, and Einstein.
If evolution isn’t true, we don’t want to believe it. We don’t have unreasonable faith in evolution — we accept it because of the massive amounts of evidence for it, and how it allows us to predict future findings (which often come true). If new evidence comes up that shows we were wrong, then we’ll happily believe the new theory.
