Maybe dinosaur's didn't eat humans.
You would have to first show that they did.
Thus, Evolution, since it cannot be disproven with science, is,(according to Popper's definition), not scientific.
What disproves Evolution is simple reason.
Something cannot come from nothing and non-life from life.
If can show an example that is indeed possible, then Evolution is viable, but until then it is just a fairy tale for adults who do not want to deal with the reality the Final Judgement by their Creator.
I believe that if you found a human's remains in the dinosaur's belly that would show that dinosaurs ate men.
You have already been informed that Popper accepts evolution as being valid science.
What if evolution is part of God's plan and he judges against those that preach falsely against his plan?
