There simply has not been enough time for the kind of evolution envisioned by the atheists to have happened. It’s been proven that the Earth cannot possibly be more than 10,000 years old. Science backs that up.
I don't think I would say "proven" - although there is certainly good evidence that supports an ~ 10k year old earth (e.g., the amount of Helium in the atmosphere given the escape and generation rates).
That said, even if you went with the 4.6B year age (I think that is the latest number that they are teaching in schools) the 'macro evolution' model that is proposed is anti-Science. Defies all experimental observations, and goes in the face of the Second Law of Thermodynamics (I know, 'the Earth is not a Closed System'... doesn't matter for the processes being proposed). And I believe as we've learned more about Genetics, the long ages (over 10k years) is contrary to the effects of Genetic mutations -- which basically imply that the destructive mutations in our Genes build up over generations to render that organism unfeasible. I.e., if I use a photo-copier to copy an original, and then copy the copy, and keep doing that (not copying the original - but the latest copy), eventually the copy becomes unreadable.
So I'd say 'proven' is too hard a word - but 10k is a better fit to the data than what is being pitched in the schools.
