"It remains possible, Kennedy noted, that animal fossils of similar or older age exist that remain to be found that are marine in origin. However, at the very least, this work suggests "that animals had already taken on the ability to deal with the environmental fluctuations one sees in lake environments," he said. "That suggests that their evolutionary response is much more rapid that I would have supposed, and that the earliest animals were far more diverse than imagined."

"One problem I have is that RNA and DNA encode information. A random collection of these building blocks may only encode gibberish but life doesn't exist based on gibberish. You have to have them in a certain sequence in order for them to accomplish any sort of purpose even accouting for the filler pieces that don't do anything but mark and fill. And this encoding of information increases the probabilities to even greater odds AND implies intelligence. These letters don't assemble themselves randomly. Someone or somthing has to put them in sequence. Even if you are able to demonstrate that life originated somewhere else, you have simply moved the location of the problem of how life originated to another planet or universe. If it didn't originate on this planet that doesn't answer the original question. And the final question then becomes, where did the matter come from in the first place from which life is based. If every action has a cause, they what was the 'cause' of matter in the first place? If matter has an age, then when was the matter 'born' and how?
Another problem is one that Darwin called 'irreducible complexity'. If proteins are the machinery of cells, the machinery of DNA replication, untwisting, proofreading, etc; then proteins would need to exist to 'manage' the DNA. But DNA is what proteins are assembled from (via RNA templates, and other proteins that work to build the new protein being transcribed, carry the amino acids, catalyse the reactions, etc). It is a catch-22 even at that simple level of understanding. And when you take into account ALL the pieces and parts of a simple cell. The myriad reactions taking place, the compartmentalization, the waste products that have to be removed, it becomes more than something you can explain with a simple roll of the dice.
I will leave any conclusions up to the individual reader but for me it is nothing short of miraculous. And that is something that science can never conclude anything about one."
