What I really wanted to address was the ramifications and implications of discovering conclusive proof of an extraterrestial intelligent agent relative to Christian theism.
Already you should be chuckling, because if the atheists are to be believed, it is not scientifically possible to reliably detect intelligent agency. Intelligent Design, we are assured, is pseudoscience at best and closet creationism at worst. On this view I suppose space aliens could land in Richard Dawkins lap at which time they begin wheeling out some of their rumored probes, and Mr. Dawkins would be unable to recognize that something out of the ordinary was happening. Anyway, as funny and as fun as that thought is, I have no doubt that hard core philosophical naturalists will have little trouble ‘reliably detecting intelligent design’ when the chips are down.
I think this is because they will expect these little green critters with big skulls to support them in their atheistic worldview. But I think that will be the atheist’s undoing. They would have been safer denying that a sentient being is conversing with them because what that sentient being actually says might compromise the atheist’s philosophical foundations.
