Sure, it's only speculative thinking. But a lot of great scientific discoveries started out as speculations too. It could be a viable path of future investigation. Also I agree that it doesn't quite answer the question of how and where and when life originated in the universe - it just pushes the horizon line further into the past. But as I said, it would settle once and for all the question whether life appeared on Earth by special creation acts of a deity or deities - thus rendering false all accounts of creation described on religious 'holy books'.
I don't like the implications of the word 'directed' either. Because it could have been a random event.
