Floods (not global, that is a whole other discussion) and ice ages are all caused by processes we can observe today. You are thinking too narrowly, it isn't the specific event, but the principles that cause the event that is the backbone of uniformitarianism. Uniformitarianism completely allows for and expects catastrophic events.
Keep those goal posts moving as much as you need to keep yourselves comfortably ensconced in your modern day ‘scientific’ theories.
There is no moving goal posts in science. There are no goal posts at all. It isn't a football game, the point is to study, observe, and extrapolate. Just like the study of gravity has gone well beyond what Newton proposed, even beyond Einstein, doesn't mean the goalposts are moving. It simply means knowledge is being acquired.
It’s Ok if you don’t want to read the website I referred to in post 19 and Buck W. re-referenced above. I’m fairly certain many others have already begun doing so and ‘ignorance is bliss’ for those who are so heavily invested in consensus science so have a good day. ttfn.
