Man has witnessed many meteor strikes. We know what the craters look like. We know what kind of debris is left. Why should we doubt the cause of the Arizona crater?
No witnesses. Can't be reproduced in the lab. Therefore it's not science. It's pure naturalist speculation. Therefore biased. Deliberate elimination of any supernatural cause.
This kind of thing will cause the end of civilization. If people start believing that rocks fall from the sky, why shouldn't we all run around raping and killing each other? Hitler believed rocks fall from the sky. Where will it all end?
