I have now spent some time nailing down what seems clear to me – without independent evidence of the designers, science has no method to determine whether or not something was designed, explaining why it is that the concept of purpose or goals has no place in science. Many will deny this. But if you can see this, then it is time for the next step.
What I have been outlining is a key limitation of science – in order for science to detect design, it requires independent information about the designer.
Without that information, science is blind to the possibility of design.
Meaning that if life and/or evolution was designed, science could not detect it.
We should pause and take that in before moving to the next step.
