So aliens are poised to invade us, according to the White House, reported HNGN recently. Stephen Hawking, Seth Shostack and Malcolm Robinson, founding members of Strange Phenomena Investigations (SPI), seem to be totally convinced about the eerie fact.

"These small grey creatures, that are roughly three-and-a-half to four foot tall, have a pear-shaped head and black eyes. These have been seen across the planet..." says Malcolm Robinson, to people gathered in the imagined Earth Space Defence HQ. 

So do aliens want to destroy the earth? Perhaps.

But what would happen when aliens do come down to touch the Earth?

Nothing nice. "The planet would be a horrible place to live. It would be bad enough having to defend yourself from the threat of an alien menace without having to worry about your next door neighbour or who could come into your house. What would become of us?" Robinson ponders. "We'd either be subject to the control of our new masters or we would make peace with them."

It's important, then, to protect ourselves. There are various ways of doing it, and Steve Hart, manager of UK Preppers guide has made a list of them. He also adds that we haven't armed or prepared ourselves for any kind of attack.

"I'm trying to cover all the bases," he explains. "All the 'what ifs' in the most compact way possible that suits me."

There could be humans in groups, or there could be individuals and lone wolves. You need to guard yourself carefully. Stack up some strong equipment, pave the way for 'bug out' locations to hide in and share knowledge among your network. 

What do you think you can do if Aliens do descend? Not much, but you can try the following things:

Firstly, stay at home. Keep inside as long as it is safe, and do not venture out. If you see some aliens prowling outside, draw the blinds.

Secondly, get a lot of water. Stock it in your house and keep a tank ready for three months.

Thirdly, do not forget the medication. Get all the the pills, potions and ointments needed to cure your headaches, tummy upsets, fears and phobias.

Fourthly, do not pile up your stores in just one place, but spread them over a number of places. They need to get distributed so that you have some back-up places to run to in case you get attacked.

Fifthly, stuff an emergency bag in your house and in your car, just in case you have to run away somewhere. So if the aliens are going to overtake us, you know you can dip into your bag, at least.

Next, be careful about your personal hygiene kits, otherwise you will be prey to other kinds of attacks - like virus assaults too.

Sixthly, be prepared for some 'bug out' spots that can help you to run to in case you get struck on the road. Steve Hart says: "I have three 'bug out' locations,  these are areas that I go to, regularly, minimally stocked up with enough supplies for a few days ... all within three days walking distance of my house, in different directions. That's how most preppers would work."

And finally, do not forget to write down the names and numbers of your doctor, supplier and local Priest - in case you get slashed. When nothing works, Pray. And if that doesn't work too - as it most certainly won't - then just let the Priest pray for you.
