Evolutionists aren't trying to disprove God. Evolution isn't even concerned with God. Evolution is science, and science does not deal with the metaphysical. That's better left to priests and rabbis.
To believe these scientists, you have to take their word on events they did not witness to explain what they admit they don't understand.
So, following you rationale, the only things that can be proved are things we can experience with our own senses. That pretty much eliminates all of physics (have you ever seen a quark?), genetics (can you see dna without a microscope) etc. etc.
No... only following your nonsequitor. We've invented a number of items to do what our senses can not. In the end, though, we rely on our senses to interpret the data presented by this equipment.
