No, and no.
No, the math hasn't been "debunked," and no, I don't presume that everything is random. Pay attention.
There are two possibilities:
1. that abiogenesis is caused by unaided natural processes, or
2. that abiogenesis is caused by intelligent, aided processes.
Either or both of the above may be true.
And yet, contrary to your repeatedly false assertation, "randomness" has nothing to do with either.
I just went to your link. The caculation is about monkeys reproducing Hamlet. It has no calculations on the probability of life.
