You call it crap because you do not understand it.
God created everything through some supernatural means, including life. Then life evolved...the 2 previous sentences are not inconsistent with the theory of biological evolution. so what.
Oddly enough, I agree with you on this statement (actually that is my current position to some degree).
Cosmology is not crap - it is the key to the debate. Many evo-reactionary attacks on creationism lack understanding of cosmology and the evidence we currently have.
From my perspective: many aspects of evolution are as good as facts. Evolution between species is on less firm ground. Biology is a science therefore it most teach the currently accepted scientific princples and theories - not religion-based explanations. When the subject of the origin of life and the cosmos (cosmology) comes up, evolution is on very weak ground and what ground it holds is purely theoretical. For this reason a disclaimer that states "No one was present when life first appeared on earth. Therefore, any statement about life’s origins should be considered as theory, not fact." is a good thing because this disclaimer states the facts and statements like this will encourage students to think rather than assume science has it all figure out. This should not freak evolutionist out because very little time in school is spend studying the origin of life and evolution does not even address the origin of life.
This thread is about a disclaimer related to cosmology (not biological evolution). Calling cosmology crap is position based solely on ignorance.
