Its called genetic variation
Evolution it aint
If the job of evolution were to simply produce allelic variety from existing genes...then we could all be happy, pack up and go home
But evolution has to create multi-cellularity from single cells, then produce every living thing imaginable via mutations, selection and fixation.....and as any geneticist will tell you...
...That aint possible in 4.5 billion years
Oh and naturalistic processes have to also create life first...still within that time frame
I can prove it is possible. Actually I already have.
multi-cellularity from single cells has already happened, therefore it is 100% certain that it can occur.
Life exists therefore it is 100% certain that it can occur.
So your little pseudo-math games are just diversions from reality.
Now lets prove that gravity can't exist. Just for kicks.
