> This is not a fact, this is a theory. This is common in 'science' that scientists believing something 'should be happening' and then attempt to pencil in details after-the-fact to explain something that doesn't fit their preconceived model.

This is exactly how science works: if something doesn't fit your theory, you adapt it so that it does or replace it with a new one. Everything in science is a "theory".
