Hi creo scientist here, I will ask this question again as i never end up with a testable hypothesis i can work on and present for people

What proof would could an evolutionist be presented with to make them evolution may not be true.

I ask this question as the burden of proof rests on the creation scientist shoulders.

So we should not hassle you, unitl we have something to show you

As we belive that dino's existed post flood, and slowly died out pre flood

our hypothesis is:

If we were able to present a lizard, that grew to the size of lets say a velocoraptor, by subjecting it to pre-flood world conditions, would you accept that as partial evidence for dino's co-existing with man, and that dino's were still around not so long ago

also if we could present you with dragon flies, like the ones you claim are 300 million years old, they types with wing spans over 20 inches by subjecting them to a biosphere based on old world conditions

would that be counted as credible evidence?

just finished watching a segment on the O'Reilly Factor (don't hold it against me) with Bill and Ben Stein (yes, that Ben Stein) discussing Stein's new movie about how intelligent design proponents are being persecuted. Bill kept asking the completely ignorant questions (Why isn't it okay to just mention intelligent design in Kansas biology classrooms, for just one example), and Stein kept spouting about how evolution was a wonderful theory for the mid-1800's and how brilliant of a guy Darwin was but his theory is filled with holes. 2 questions: 1) Is there any research being done to support ID, or predictive power of the "theory", or any scientific basis for it (I'm pretty sure I know the answer to this)? and 2) Is this movie on anyone's "must see" list (the movie is called "Expelled: No Intelligence Allowed")?

okay so i am a pta major and i am in anatomy and physiology right now and we are doing muscle contractions right now and i just DO NOT GET IT. so if anyone could explain it to me that would be wonderful...

this is what i have in the way of notes for it:
-motor nueron action potention
-acetylcholine release and binding (to motor end plate)
-action potential in sarcolemma
-calcium release from sarcoplasmic reticulum
-exposure of actin active sites
-binding with myosin cross bridges
-reset

i mean i kind of get it..like i know what the sarcolemma and the SR and myosin and actin is..
i dont really understand what action potential is though

any help at all would be GREATLY appreciated!!!!!!!!!
