Ah, I see... I apologise, I thought we were discussing evolution, but you seem to be talking about abiogenesis.But the big one is you are suggesting life coming from non-life. From rocks to frogs.
Sounds outlandish. You have the burden of proof.
No matter; let's examine the available information to see who most likely has the burden of proof for the origin of life:
For abiogenesis - we see no signs of life in the earliest rocks, and a point where the first signs of extremely simple life appear. From this point on, there is a progression in diversity and complexity of the life forms we see preserved in the rocks. This suggests that life began very simply and became progressively more complex and diverse.
This progression is consistent with what we know about how populations of contemporary life forms change over time (i.e. evolution), and the theory that explains it. We also know that some time prior to the earliest signs of life, the Earth was too inhospitable for any form of life as we know it.
So the evidence suggests that life started in a very simple form when conditions on Earth became suitable to support it. We also know that life is dynamic organic chemistry, and that all the components necessary for life were present in the environment. We also know that, under the right conditions, many of the chemical components for life will self-assemble into structures similar to those found in the simplest cells, and many of the reaction cycles found in living cells also occur. Evidence also suggests that there were a number of environments that seem well-suited to providing those conditions.
The claim of abiogenesis is that, if it is possible for a simple replicator to emerge from the chemical interactions of these 'building blocks' of life under suitable conditions, then given the potential number of suitable environments across the whole planet, and a time period of thousands of millions of years, or more, in which it might happen, even if any one such event was unlikely, it would be almost certain to happen at some time and place.
So what about the ID argument for life? As far as I'm aware, we have no evidence of any intelligent entities being involved at any point, no reasonable idea of what such an entity might be, or how it might produce life. It's purely speculative (feel free to jump in with plausible suggestions).
Given the choice between the possibility of a plausible naturalistic explanation, and invoking a speculative unexplained intelligence for which we have no evidence, it seems clear to me that the burden of proof is with the latter - and I think Occam would agree. YMMV.
