Was Life On Earth an Alien Creation?

It's a new article I wrote available at DB Skeptic. Here's the introduction:

"Life may have been the result of intelligent aliens sending bacterium to Earth. This theory is called “directed panspermia”. It was proposed thirty-five years ago by Francis Crick, co-discoverer of DNA, and Leslie Orgel, a highly respected British chemist. I found the original paper they published. Here I examine it and provide some comments."

By the way, this post is my 500th!!
