Oh, actually, that has probably happened many times. We carry what are probably ancient viruses in every one of our cells. It's amazing.

It's that probably that you stuck in there that trashes everything else you said.

From a scientific viewpoint, that is.

From a philosophical point of view I'd be very interested in discussing the suggestion.

Shalom.

"From a philosophical point of view I'd be very interested in discussing the suggestion."

I'm afraid that my knowledge of viral remnants in evolutionary history is too small to take on the discussion.

You can Google it, though. Google "viral remnants evolution" (no quotes). That will bring up a number of sites which get into this area of evolutionary research. It's quite fascinating, and is growing as a sub-discipline.

I'm afraid that any attempt I might make to go much deeper into it would lead to errors on my part, so I'll leave it to you to investigate for yourself.
