"What claim of modern science belies the theory that we are visited by beings from other planets?"
As one prominent scientist asked, "If they're here, where are they?"
You can't find them in your living room means they aren't here? Does an ant know when you are watching its anthill? How is this a scientific demonstration of anything? Pretty ludicrous for you to be claiming you stand on firm scientific grounds regarding ID, based on the proud claim that you can't prove there wasn't intervention, whereas you reject the most obvious explanation for intervention, based on the exact same argument.
As you've just demonstrated, ID is a joke, not a science.
