No one in geology has ever denied the possibility of asteroid impacts. The problem with catatrophism as it was theorized 50 years or more ago, is it attempted to explain what are obviously gradual processes. In the entire history of the earth there are only a handful of suspected worldwide catastrophes. The 1908 impact was a blip.

When I had the sciences 40 to 45 years ago. There was no discussion of catatrophism except to say it was refuted. That is why I brought up the "return to catatrophism" topic. Of course there has been few world wide disasters in the history of the earth. If many more we would not be discussing this topic. Personally the modern catatrophists have convinced me.

By the way now that we are discussing the topic If I recall correctly catatrophism was believed "put to bed" circa the 1840's to 1860's. If inclined I'll look it up in an old geology text from the late 1950's. This is one of the advantages of age-not too many advantages though.
