Wow!! You go out of your way to get things wrong.
How the scablands were formed was not known. The idea of massive floods was unsupported by other evidence at that time. They did not say "it took millions of years". They simply said "I don't believe your explanation because it is not properly supported by evidence". Guess what happened when more evidence was found? They changed their minds.
The Wiki article on the Channeled Scablands tells you why his interpretations were not accepted at first:
" His theories of how they were formed required short but immense
floods – 500 cubic miles (2,100 km3) – for which Bretz had no explanation."
Bretz himself had no explanation where the water came from. That will get you laughed at when you make almost any claim of the sort that he did.
Meanwhile you follow people like Ken Ham who lost the debate with Bill Nye when he said that no amount of evidence would change his mind. And in fact he makes his employees swear not to rely on what the evidence says.
Your bad behavior indicates fear on your part. Why are you so afraid of reality?
