It was an accident that i discovered their failed invasion of the past. Their dead bodies were attributed to a mass suicide. My instruments detected that they were aliens.

My curiosity lead me to discover that they were from another dimension. I went ahead a few years at a time until I discovered their second attempt.

I discovered that they were testing items that had the potential to destroy the bacteria in the human body that posed the threat to them.

Unfortunately for humans the procedure would be fatal to their consciousness. It would however leave the rest of the body functioning efficiently.l

The invasion began yesterday.
