Intellignt Design is the oigional therom , Evolution is the upstart.
Now that is just entirely untrue.
There was no original "theorem", just a belief that the entire universe was created in a week around 400 BC.
Intelligent design is not a theorem, either. It is speculation, written as Biblical "research" is done. The Bible is assumed to be true, then we are supposed to consider how this could possibly be true, considering all the evidence that evolution did, in fact, occur, but God was in charge of the entire process.
Evolution, as a scientific view, is always subject to research and elaboration. But intelligent design is not science nor even scientific.
No true scientist takes it seriously.
