> "The two researchers acknowledge their ideas are more of a "thought exercise" than a theory proposal, but at the same time suggest their calculations ought to be taken seriously. They start with the idea of genetic complexity doubling every 376 million years—working backwards, they say, means that life first came about almost 10 billion years ago, which of course predates the creation of Earth itself. Most scientists agree the Earth formed just 4.5 billion years ago. Assuming that Moore's Law does apply to biological complexity, this would suggest that life began somewhere other than on Earth and migrated here."-Matt Ridley reviews (WSJ) this discussion. Same old problem: "Does that mean life is common? No. We still don't know if it's very easy or very hard for life to emerge from nonlife even in the right conditions". Ridley avoids the obvious from 60 years of research. Life is extremely hard to get started as a large group of intellects in various labs have shown.-http://online.wsj.com/article/SB10001424127887324874204578438701489800128.html-Panspermia solves nothing. It just removes the origin of life problem to outer space.
