The Red Rain of Kerala

When most people think of aliens, they imagine super-intelligent grey-skinned humanoids or slimy, multi-tentacled beasts. But what if Earth has been repeatedly visited by extraterrestrials no larger than a single cell? That's what some believe happened in India between July 25th and September 23rd, 2001.

It was during that time that the Indian state of Kerala experienced an unusual phenomenon. The annual monsoon rains turned red--blood red. Clothes were stained, puddles turned scarlet, and people were frightened. It wasn't long afterwards that scientists set out to study the bizarre liquid.

Of course the Kerala red rain wasn't the first time strange things have fallen from the sky. There have been well-documented accounts of frogs, fish, and birds raining down from the heavens. Such events, while unusual, have a logical explanation. At first, many assumed that a similarly simple explanation could be found for the red rain. Perhaps an Arabian dust storm had been sucked into the clouds and deposited over India. But then they put the liquid under a microscope.

The particles that had turned the rain red didn't resemble dust. They looked like living cells. Most mainstream scientists eventually concluded that they were spores or algae. Others, however, claimed that the "cells" came from outer space.

Not long before the first red rain, residents of Kerala reported a loud boom and a bright flash of light. These reports led a few scientists to speculate that a comet entered the Earth's atmosphere that day, carrying the red particles. When the comet disintegrated, the red extraterrestrial particles became trapped in the clouds and later rained down on Kerala.

So were the red "cells" the first evidence that Earth has been visited by alien life forms? Read more here, and decide for yourself!
