I guess then we'll have to throw out anything relating to plate tectonics, star formation, and more. Can't test them in a laboratory you know.
Of course in the laboratory we COULD test how ERV virus DNA gets into genomes. And we COULD test to find such DNA sequences that exist in primates and humans. And we COULD conclude that these got there from common ancestors millions of years ago. But you, being the arbiter of what is, and is not "science", restricts us from concluding anything from those observations.
Sad.
This is why ID theory really means the end of science in the modern world. Because entire sections of the natural world are locked away by political/religious ideologues with agendas.
It's just good that genuine scientists ignore people with such agendas.
The laboratory is as big as space, and the instruments are various types of telescopes. But your observations come with a preconceived bias against God and against Him having created things just as you see them. That causes you to believe that God could not have created the universe with apparent age. For example, your bias prevents you from believing that God could have created a star hundreds of thousands of light years from earth with the light already reaching earth at its creation. Your bias prevents you from believing that primates and humans have a better than 90% similar (DNA) genome by deliberate and specific creation of God, and yet they were created as separate and distinct creations.
