Yes, you are right. The genome is a battle field between human reproduction and viral sequence integration and reproduction in our “shared” genomes. We think of it as a human genome but it is hodgepodge of what we call “our” genome and half a million viral-derived sequence that also wants to replicate every once and a while.

Eukaryotic genome are the worst noodle code you have ever seen—but miraculously they help to make humans and other creatures, bugs, and plants with some consistency. That is a miracle to even the most hardened atheist!
