I'd be interested in seeing the math from which you derived this conclusion. Please enlighten us with your probability model for the origin of life. However, I detect the presence of an argument from personal incredulity so I won't get my hopes up.

An unobserved (past or future) event can reasonably be declared impossible without calculating the mathematical probability of that event. The mathematical probability of some unobserved events, be they deemed possible or impossible, cannot ever be calculated.

Furthermore, even if the probability of an unobserved event can be calculated, we still may have no way of knowing if is possible or impossible (for example, if the probability of a certain event is calculated to be one in a trillion-trillion, is the event possible or impossible?)

It is reasonable to declare it impossible for my house to be struck by a brick-size meteorite every day for a year, even though the mathematical probability of such an event occurring cannot be calculated.

It is reasonable to declare it impossible that the action of waves crashing onto the sea shore will ever arrange sea shells on that shore to read out my full name, address, age, occupation, home and email addresses, phone number and bank account details, even though the mathematical probability of such an event occurring cannot be calculated.

It is reasonable to declare it is impossible for a forest to ever build a log cabin, even though the mathematical probability of such an event cannot be calculated.

It is reasonable to declare it impossible for baboons to ever build a space craft and fly it to the moon and back, even though the mathematical probability of such an event cannot be calculated.

It is reasonable to declare it impossible for dead matter to ever arrange itself into a self-replicating, living machine within a few hours (ie, before it dies), even though the mathematical probability of such an event cannot be calculated.
