A few years ago physicist Stephen Hawking shook the scientific community with his views: That the human race could be devastated if aliens were to learn of our existence and venture to Earth, he warned.
But could, or would extraterrestrials really invade Earth?
Aliens have already viciously attacked our spacecraft, savagely kidnapped us, heartlessly conducted experiments on us, and mercilessly aimed their death-rays at us. But of course, all of these crimes have been committed only in our Science Fiction books and movies.
Other experts who, like Hawking, have devoted their careers to thoughtful exploration of the possibilities of alien contact say that we don't have anything to fear.
These scenarios play on our most primal human emotions of losing the resources we need to survive, among other fears, says Seth Shostak, senior astronomer at the Search for Extraterrestrial Intelligence (SETI).
In reality, it isn't logical to think that aliens would want to do either of those things, he said. Anything that we have here, they could find where they live, If there was a resource found on Earth that did not exist on the aliens' home planet, there would certainly be easier ways to get or make the resource than coming here to ravage our planet, or other less evolved ones.
We're listening, Morrison said. And we can assume that any civilization that we receive a signal from is more advanced than we are.
Morrison doubts that an advanced alien civilization would come here to harm us in the first place. If a civilization can last for hundreds of thousands of years, it almost surely has solved the problems we have.
Even if aliens knew about us and could travel here they wouldn't be likely to send an army or the equipment needed to launch an attack on the Earth, says Science Fiction author, Jack McDevitt. Although contact between humans and aliens has been a key part of many of McDevitt's books, he doesn't think that it's likely to actually happen. Any civilization capable of this feat would not want to delegate its fighting force to the task, he said, We have bigger problems to worry about than aliens attacking, McDevitt added.
But on the other hand...
Watch for the second part in this post called Ancient Aliens. Including a look into the third Soul-Love book, Distant Vision.
