Don’t bad theories get replaced with good ones?
Frequently -- and the good "development" theories define what they are "developing" before they start. Otherwise they are operating "with a blank check" that can be filled in by any and every investigator...

Add that to your "Theory of the evolution of [undefined] "life"...
Not if their proponents shout, "Deniers!!!" at those who offer alternatives -- instead of considering their data...
Like Nye does...
