It was a good lecture today, and I bought Seth Andrews book, DEconverted. We opened up for questions at the end and as could be expected, there was a young earth creationist who attempted to wax eloquent with his nonsense that was mainly centered on the supposed fact that life can only come from pre-existing life. He also maintained that multiple century lifespans, talking asses and serpents, etc. were absolute truths.
It's true that we have not yet been able to replicate the creation of life from inanimate elements and the only life we are now aware of has to have its origin in pre-existing life. Maybe we never will be able to do so, but I'm not so sure. One thing I do know is that any research in that area has to be carefully controlled lest we unleash something on the world neither we nor the eco system is ready to deal with. We're going to also have to be very careful about bringing anything back from other celestial environments since our experiences in taking things like mosquitos to Hawaii in water barrels carried on ships and other invasive life forms to other places has been catastrophic enough. Something from outer space could be immeasurably more disastrous!
It's a stupid argument carried to its ultimate, since a deity would have to also come from something that pre-existed it, etc., etc. We just don't know how the universe arose, but this video I just listened to brings up some interesting possibilities to further bogle the mind:

Why is there something, rather than nothing? This question has long been the domain of philosophers and theologians, but science can now finally weigh in. Ph...
