Would you care to mathematically corroborate the number of cases where "some complex objects self-assemble from random components without intelligence or design" vs. the number of cases where complex objects otherwise exist?
Never mind. I know it is outside your capacity to produce an accurate corroboration in this regard, and I won't hold either your inability or refusal to do so as a proof of any kind. I am not in a position to claim scientific absolutes, though others seem to be.
Doesn't matter. As long as there is one instance where a complex object self assembles, the assertion that complexity requires design is refuted.
