I have not seen anything stated about this in the current thread so I thought I would make mention of it.
In short, mathematically speaking, it is impossible for life to come from non-life.
Given the enormity of the 'age' of the universe, still one does not have enough time or probability for proteins to be developed on their own by chance, let alone DNA.
It's one thing to look at the present circumstances and say, "Because we are, it must have happened." But it is a completely different ball of wax to say that it really did all by chance.
I am sure that DNAunion can attest to the intricacies of DNA, and the difficulties that arise when trying to consider this all just coming together at the right time and making life.
If asked, I have documentation showing statistical evidence that the chance of life from non-life is nil (10 to the power of 1.4 million).
