I do have knowledge it will occur. The trend in knowledge and technology shows it to be inevitable. When we know enough about the mechanisms of genetics and we have fast enough computers then we can simulate organisms on computers. We won't need to use live organisms anymore, and there will be no time constraints as we wait 2 years for the next generation. Evolution of an organism's genome over millions of generations will be testable. Therefore evolution will become directly verifiable. It will either fall, or it will be verified beyond doubt of anyone.
No, you have faith that it will occur. You believe it will be so, but you don't have knowledge that it will; unless you are God or God revealed it to you.
The math types here will point you to a singularity.
There really are places you can't get to from here!
There are statements of faith in the bible that are expressed as "I know...". It is common that someone's faith becomes strong enough that they express it as knowledge.
It is appearant that you have strong faith in Darwinism.
The Apostle Paul, in the New Testiment, defined faith as hope in things not seen. Your faith follows that definition.
As far as any simulation, the program must contain assumptions which determine to a large extent what the simulation will do.
Your faith is that the assumptions are true and therefore the predictions will be true.
There are many programs that make predictions. Weather is one of them. If data from ten years ago is entered, the program does not accurately display what actually happened.
Simulation programs are useful, but to place faith in what they will show is no different than placing faith in the book of revelations.
It is ok to have faith, and statements of faith are fine within your community of faith, but to require your faith to be taught as science to the exclusion of all other teachings is presumptious in the extreme.
