The issue isn’t as much biology as it’s mathematics.
You don’t need an English professor to you tell you how long it would take a monkey to randomly type out the works of Shakespeare, you need a mathematician.
Darwinism posits that the changes are the result of random mutations. And scientists who understand mathematics are saying it will take much more than 4.6 Billion years for the amount of random mutations to occur that can explain complexity of life on earth.
No mathematician can effectively model evolution without understanding the underlying mechanics of DNA mutation and all of the forces impacting "random" mutation.
We're still discovering factors that appear to influence the type and location of these mutations so the idea of someone not versed in the field being able to create a predictive model is a non-starter.
Succinctly and brilliantly put. Thank you.
