How does running into a wall provide evidence for the existence of atoms? If anything, it is evidence against their existence. And your light-hearted example of falling off a cliff does nothing to demonstrate Newtonian universal gravitation let alone relativistic gravity. Nor does it provide an inverse-square law or a value for the gravitational constant. And, if I know nothing about gravity, all it shows is what happens if I fall off a cliff.
The average person does not “observe” evolution. It might be obvious now, but it took some extended and unusual trips by Wallace and by Darwin to formulate the basics of natural selection, and it took a lot of research in geology, physics, and genetics to provide the additional support.
Yes, evolution is a fact. Proponents of Intelligent Design accept the fact of evolution but they introduce a supernatural element that takes precedence over genetic drift and natural selection. A slightly more meaningful question for this thread could be: If genetic drift and natural selection were found to be wrong, would you believe in God? There would still be no connection with a belief in God and there would still be the same objections raised in this thread but at least the topic would be a bit more focused.
I think that some people in this thread are arguing in a way that is similar to how some Christians justify the existence of God: The Bible says so. Okay, but why believe the Bible? Because God wrote it. How do you know? Because the Bible says that is inspired by God. Uh, what do you mean by “God”? Well, let’s take a look at what the Bible says …
Anyone who accepts the fundamental principles of modern science must accept the basic conclusions of modern science. Evolution through natural selection is one of those basic conclusions. If it is wrong, then there is something fundamentally wrong with modern science. Which is exactly what some Christians say. To argue that natural selection must be right because … because it is … is like saying that God must exist because it is obvious that God exists. And, not only is it obvious that God exists, there are many, many people who agree that God exists.
Evolution (specifically, speciation through genetic drift and natural selection) is not obvious. Neither are geocentrism, universal gravitation, relativity, or quantum mechanics. There are plenty of reasons for doubting their validity. But, there are more reasons for accepting them as true. Within the model of modern science, it makes sense to accept them as being true, so I accept them. But, there are alternative models that make sense to some people. Not to me.
