Does nature have a sense of humour?
Millions of years ago the T-Rex meat-eating dinosaurs might have hunted the ancestors of humanity; now, the T-Rex has evolved into a chicken and our ancestors into KFC-loving chicken-eaters. Nature seems to have a dark sense of humour.
When I observe that life loves to go-forth and colonise, like dandelion seeds upon the wind, what if our planet is a living organism and has similar intentions of sending forth its own genetic code to colonise other planets? What if human beings, who consider themselves the superior life form on earth, are mere containers designed to ship bacteria off to other planets? It would be funny to think hubristic humanity is no more than shipping containers designed for shipping bacteria to other worlds, it would be typical of the sense of humour of nature.
