Be as skeptical as you like. It is fine. I am probably more skeptical than any of you on most subjects. This one, however, is sound science backed by one of the most careful experimental physicists of all history.
Just for the record, I think this asteroid theory is as good as any I have seen. It’s a little like arguing about the existence of god. Many things point to gods existence but none can be proven.
It’s not even empirical science! It’s historical iow it can not be tested/re-produced therefore it is highly subjective. The hypothesis is just the best guess so far.
Folks that talk like you seem to think science is a deity and has already solved most everything. The fact is the body of knowledge that we don’t know is at least 100 times larger than what we do know. And some stuff we may never know.
But please don’t let any of that stop you from beating your chest. /s
