Aliens in Paradise?

My paradise isle has been attracting all kinds of tourists. Some come with their sweethearts, some come with their families. The Dutch, the Portuguese and the British came with their armies, and didn't leave for centuries.

The latest, it seems, are the aliens.

Saw some news reports indicating that there had been some alien sightings in the Southern Sri Lanka. There were the landing marks, crop-cirles, pictures taken from a mobile phone etc. etc. to back-up the claim.

"Do you believe in aliens..?" a friend asked me.

I told him that I don't believe these particular reports, but I wouldn't disregard the fact that there could be some other life forms in this universe. After all, the earth is just a grain of sand in the desert.

I think the problem is that most people are "pre-conditioned" in this day and age - they have read about aliens and already have formed an opinion and a visual impression of the strangers from the outer space. So it's very easy for one to describe the sight - and more often than not, they all tell the same story:
Big eyes, small figure, proportionately larger head... all too familiar and seem to be in line with X-Files and "Bhavathra" (the local version).

Look at this planet earth. There is an umpteen number of different life forms that roam the earth. So, why can't the aliens be present in the form of a... say, a bird, a beetle, a snake or a chimpanzee..? Why must be they imitating the human figure..? Why only stop at fauna - why can't be there any alien flora, growing somewhere in my own back yard, transmitting some sort of signals to the outer space..? How amazing would it be to discover that the little dung-beetle in the garden is an alien..?
