Human Flash Drives?

Recently, scientist have learned how to encode messages into the genomes of multiplying bacteria and then accurately retrieve the message 100 bacteria generations later. The message is automatically replicated when the bacteria reproduce. Here is one article on the research: Data stored in multiplying bacteria

Why did scientist do this? Because data stored in the usual electronic places, like hard drives, CDs, tapes, etc, can eventually be lost or destroyed. Scientist were looking for a different place to store data. They came up with a biological storage solution, DNA.

So, I started thinking... What if this technology was perfected and performed eons ago by intelligent visitors to earth. What if they stored their important messages and data in... the Human genome!

Wouldn't that make each of our bodies a flash drive for some alien race? Will they ever come back to retrieve their data? mmm...

Food for thought...
