Not exactly aliens, but microbes.

In April, Louis, a solid-state physicist at Mahatma Gandhi University, published a paper in the prestigious peer-reviewed journal Astrophysics and Space Science in which he hypothesizes that the samples -- water taken from the mysterious blood-colored showers that fell sporadically across Louis's home state of Kerala in the summer of 2001 -- contain microbes from outer space.
Specifically, Louis has isolated strange, thick-walled, red-tinted cell-like structures about 10 microns in size. Stranger still, dozens of his experiments suggest that the partiacles may lack DNA yet still reproduce plentifully, even in water superheated to nearly 600 degrees Fahrenheit . (The known upper limit for life in water is about 250 degrees Fahrenheit .)
So how to explain them? Louis speculates that the particles could be extraterrestrial bacteria adapted to the harsh conditions of space and that the microbes hitched a ride on a comet or meteorite that later broke apart in the upper atmosphere and mixed with rain clouds above India.
I be surprised... I would not have anticipated this. Shows again how science is superior. I bet people thought the blood
rain was a vestige from God.
