I only heard the last hour or so. Hoagland thinks that life began on Earth almost immediately (which I'm not sure is true) and was seeded by a "lonely alien intelligence" that wanted some company. Non-commital on whether or not that intelligence is "God". There was some other goof on there saying something about the letters of ancient alphabets having creative power - I missed his fuller explanation, but even his other guests weren't buying what he was selling.

It was enough to make the Discovery Institute burst a blood vessel.
